A four-fold 'star' pouch (origami design)

2011-09-03T11:47:00.000-07:00

Here's a design I came up with a few years back - it is published in this year's Origami Fold-A-Day Calendar, as the entry for December 1:

As you can see from the crease diagram (marked '3.' above), the shape results from a set of symmetrical crease patterns, which you draw on your sheet of paper and then fold along - the final shape almost creates itself :) Here is the crease diagram again, with each fold marked to be a 'v' (valley) or 'm' (mountain). Fold the '1's first, followed by '2's, finally, the '3's.

A blast from the past - this is a t-shirt design that Mary-Margaret and I submitted towards the SIGGRAPH '98 T-Shirt Contest, it won first place :) Shown is an entry about this, from Mary-Margaret's site (click on the pic to bring up a bigger version).

Let's go CLUBbing..

2009-11-01T16:52:00.000-08:00

Imagine this - you pick up/walk up to an Internet-connected device, and run a mini browser that brings up a simple login screen. You log in with a username and password, then you're 'in'.

In what? In an environment where you can run tens of thousands of latest (or older) programs, including web browsers with access to millions of sites as usual. Run the programs where? Somewhere on the 'cloud'. You work as usual, opening software, creating content, editing, saving. Saving where? On the 'cloud' again. Then you simply log off when you're done.

Login again (from the same device or another) and all your stuff (content, shortcuts..) are all there right where you left them. Resume working/playing :)

What I've outlined above is radically new, it does not exist today.. But it could, and should. It is "utility computing" in its fullest sense, where the local (access) device STORES NOTHING, and much more importantly, RUNS NOTHING. Note - this isn't Google Docs, Photoshop Online or dozens of similar things where you run software ON your machine and store the results online or locally. In my scheme, *nothing* happens locally at all, except transmitting of simple data upstream to the cloud (key clicks, mouse events, other device data) and reception/display of video/audio - specifically, all the "computing" (*ALL* the computing) happens elsewhere, so does data storage. The user's device is simply a 'dumb' window into this infinitely-capable 'cloud' infrastructure where all the action happens. Skyfire is a mobile browser that works this way somewhat, but it's limited to website-based content.

With the above scheme, these things become possible:
* ANY device, ranging from a $10 cellphone with a little cheap 1" OLED screen to a netbook to a large screen touch-enabled desktop can tap into a vast wonderland of software. Obviously, the user experience will scale up with device capabilities but even the low-end ones will still let me move mountains
* ANY/ALL software is run *ONLY* online in massive, powerful, utility server clouds, using, as far as I'm concerned (or not) 'gobs' of RAM, 'unlimited' disk space, 'high-end' processor resources etc. The user doesn't know or care what is being used, since it *looks* as if things are run locally. THIS IS THE KEY IDEA.
* software vendors that participate in this scheme can make available, to millions of users simultaneously, their latest offering with up-to-date bug fixes and new features
* users will have minimal (zero?) need to install anything locally. Software piracy will go away (since the home software market goes away) as will the need to constantly 'upgrade' OSs, disk space, RAM, devices, drivers, plugins..
* in addition to the usual things that people will run on the cloud (word processors, presentation creators, spreadsheets, database software etc.), much more richer/specialized software become equally easily available:
- 3D and 2D content creation programs - everything from Maya to Flash
- video and audio editing software
- engineering software (CAD etc.)
- mathematical software, eg. Mathematica
- publishing software
- Second Life, Google Earth..
- for programmers - environments for dozens of languages
- games! Why own a Playstation/XBox/Wii and their associated
cartridges and I/O devices?
- for kids: flash cards, early reader books, musical toys, interactive globes, vocab. builders, etc. - there are literally hundreds of toys that need batteries, come with their software (sometimes as cartridges), etc. All (ALL) of these can be run remotely.. So can tens of thousands of Flash-based (for example) games that are out there
- science and math demos, practice exams etc. for older kids
* browsers that you run on the cloud can grab data (including A/V) from sites that you visit, *way* better than you could hope to using your own machine, reformat them for your screen and simply send the A/V to you. No need for you to install and upgrade browsers and an endless parade of associated plugins (eg. Flash, Java). Also, no local software execution means viruses on your machine are HISTORY!
* device piracy/damage doesn't matter - your stuff will still be safe centrally 'somewhere', backed up regularly, stored strongly encrypted
* no 'syncing' between anything and anything else, ever
* paradoxically, even as software piracy will cease as an industry, end-users WORLDWIDE will have access to way larger collections of software and content than they can ever dream of locally owning. For software vendors and CSPs, this in turn would mean truly global revenues
* by feeding out A/V (and possibly control signals on appropriately enabled devices), various things like animated walls of pixels, theatrical projection, DJing etc. become possible using cheap generic access devices (this isn't a new idea - I'm just saying that as part of the utility renting, **all** music, movies, books, and other forms of media should be centrally and simply accessible as well)

As you can see from the above, you will be able to do anything from anywhere, using almost.. nothing (just a trivial device to let you log in). This will democratize net and software and content access worldwide (all is needed is a broadband connection, not even 'OLPC's - even users in podunk little countries have cellphones, that's all is needed). Likewise, parents can enable levels of powerful filtering on the virtual desktop, allowing kids to surf safely.

Also, payment can be based on hours used, software resources, data storage and other metrics. The user pays a single utility computing bill, perhaps to their ISP. Vendors (CSPs, "Computing Service Providers") can offer tiered rates, seasonal promos, free/cheap off-peak rates, etc. CSPs can look to phone/cable/gas/water/etc companies for ways to charge for their offerings.

Collaboration on creating any kind of content (books, 3D graphics, music, videos) etc. will become a reality, not just sharing of docs etc. as is currently enabled by Google Docs etc.

So how about CLUBing it? Companies like Google (especially Google!) can use their existing browser to provide you a single login link. When you log in, your virtual desktop is displayed as a browser page, and you're in business. In principle, this can all be done right NOW!

Does the above remind you of VPN? That's pretty much what this is, VPN for Everyone. It's like being able to access stuff in your home computer 24/7, but way more convenient and secure. Also, we're starting to access ("consume") movies, music and books online, software (which includes games) is the next logical step.. Also, "newspapers", magazines and similar content can all be available for browsing and reading, with the reader paying per article/page or based on time spent.

Summary: don't send data to my browser to render, send me just pixels instead, using a new alternative to http. In other words, it's being able to run, for example, iPhone apps without an iPhone (would need a touch-enabled device but doesn't have to be an iPhone).. Update, 1/27/10: another overhyped device from Apple ('iPad') debuts today, another piece of hardware that can be obsoleted by the above scheme.

PS: Oops - almost forgot: CLUB stands for Centrally Located Universal Browser..

PPS: Relevant related concepts/initiatives, old and new:
* VPN
* OnLive
* Gaikai
* Steam: http://store.steampowered.com/about/
* VDI - Virtual Desktop Infrastructure
* IAAS - Infrastructure As A Service
* Skyfire etc. - server-rendered browser content
* Salesforce.com
* Mental Ray - RealityServer
* Houdini (Side Effects) - cloud-based rendering via HQueue
* SGI's Cyclone - on-demand cloud computing service
* Citrix's Receiver+ OK Labs' microkernel hypervisor: Nirvana Phone
* Cerelink
* VFX in the cloud
* Typesetting service
* OnLive cloud..
* AXIS: TV graphics
* Project Photofly
* Fabric Engine [tangentially related..]
* ColorCorrection.com [not quite a 'cloud' service; it is more a 'web-based' one]
* RenderMan-On-Demand - high-quality photorealistic (or 'non') renders off the cloud :)

PPPS: Here is an idea for the hardware side of this - a little 1" cube that projects (at an angle) its display on a flat surface (just like SixthSense but simpler), and has a camera that can pick up finger-based taps/clicks on the projected image. A headphone jack and a built-in mic and some ports will round out the features. With this, you can carry a teeny device in your pocket, with NO MOVING PARTS! Add to this a 'shakeable' (to charge) battery and a fully wireless-enabled infrastructure (LTE/WiMax etc), and it's digital nomadic heaven. Play with/look up/work on/interact with anything/anyone/anywhere/anytime.

Bottom line: AAADRRR - *all* *apps and data* reside/run remotely.

Steal these inventions!

2009-01-04T15:39:00.001-08:00

“As we enjoy great Advantages from the Inventions of others, we should be glad of an Opportunity to serve others by any Invention of ours, and this we should do freely and generously.”
- Benjamin Franklin

Over the years there are many, many things I've invented 'in my head', have never taken them through the steps of prototyping, patenting, building/licensing etc. Here I'm going to start cataloging them. Feel free to do whatever you want with them..

LED Christmas lights

One of my first ideas.. Since mid-80s I've been talking about these. Now they've been in the market for a few years.. These additional things are still possible:
* create interesting sequences for lighting a string - blinking all on/off, 'chasing' sequence, alternate ones on/off, switching on/off according to color (in a multi-colored chain), etc. These are even more effective when the chains are folded into 2D and 3D patterns (eg. stars, snowflakes..)
* create LED grids (eg. 30x30) that display Lite-Brite type of pre-programmed patterns.. A controller box makes it possible to cycle through patterns at varying speeds, make them blink or form in interesting ways (eg. top to bottom, radially outward..). A variation would be to include an SD card reader, to allow users to input their own patterns.

A 'trip-cam' for cars

A very simple flash-memory-based camera that plugs into the cigarette adapter, sits on the dashboard, looks outside and continuously takes 5 fps video (plus audio). The memory is used in a 'loop' fashion so that when the end is reached, recording continues at the beginning. Great for documenting trips (esp. in case of an accident).

AAA to AA battery adapter

Seriously.. a AA form-factor 'holder' whose top unscrews flashlight-style, to accept a AAA battery. What's the point? In a pinch, to use AAA batteries in AA compartments, when there are no AAs handy. As much of a no-brainer as this is, I'm unable to locate a patent for something like this :) When faced with this situation, I've made do with 'aluminum balls' (made of al. foil) in the holders to 'promote' AAAs to AAs. But a more robust solution would be nice.

Tire gages built into tires

A miniature indicator showing tire pressure, built right into a tire's valve. [Update - my friend Satish points out that luxury cars have had this feature since 2002].

Photochrome-treated windshields

Again, I'm surprised this hasn't been invented yet! A tiny amount of photochrome pigment blended into the windshield, esp. in the upper part would do wonders for reducing glare during morning/evening driving, when the rays of the sun shine at a near-horizontal angle.

Toothbrush with a UV source near the bristles

The UV light is for making yuckies fluoresce and/or killing bacteria. [Update - just saw this (10/16) in the 'abc distributing' catalog, listed as 'Germ-Free Toothbrush Cases']. [Another: Violight].

Stereo glasses with wireless receivers

Glasses receive left/right eye imagery broadcast from a server! This has the great advantage that we can do away with screens (movies, PC, TV..) altogether (and for movies, projectors)! Movies (encrypted, encryption changed each time) can be "shown" anywhere - malls, the beach, fairgrounds, college campuses..

Solar-powered car A/C

Idea - use the sun's heat to keep the car cool.. Getting back into a parked car that's been sitting in the hot sun - does not have to be painful! A small solar panel that can generate 12V and decent current should be able to power a small A/C unit or just a simple fan. Even LCD panels overlaid on windows/windshields might help keep the car cool - they would be darkened using the solar energy.

Borromean rings

2009-01-03T22:09:00.000-08:00

These are quite interesting..

Here is an animation:

The color scheme employed is that of a ChromaDepth palette. The scheme makes it possible to create 3D (stereo) imagery for viewing with special prism (diffraction) glasses. But a lot of times stereo can be perceived even w/o glasses by looking intensely at the images long enough :)

Autologlyphs

2009-01-03T18:19:00.000-08:00

Coined by Henry Segerman, the term 'autologlyph' is a self-referential image illustrating a mathematical concept. His collection of autologlyphs is here. Here's my contribution:

There are many more autologlyphs I've been wanting to create.

Eradicating homelessness

2009-01-03T16:01:00.000-08:00

Large numbers of people worldwide are homeless (live outdoors, under bridges, inside abandoned water pipes, sleep on park benches..) or live in shantytowns, in makeshift shelters constructed out of cardboards, wooden packing boxes etc.

I've always thought that the sorts of storage sheds shown below (for US homes, manufactured by Rubbermaid and others) have the potential to be repurposed as sturdy dwelling units for people.

Solar panels integrated into the roofs of structures like the above would help offset some electricity costs.. Low cost devices like the ones below (again, sold in home and garden centers in the US and elsewhere) can be scaled up to create free-standing lamp poles to line streets.

Thankfully now there are designs like the Abod that are moving us towards the dream of "solving" homelessness.

Also, this is a step in the right direction.
