Found Footage: $2 multitouch screen, made with iSight
Multitouch is all the rage lately, but one of the drawbacks is that it's still pretty expensive. Enter this ingenious device-- it's a bag with dye colored water in it. That bag is then laid flat on a glass table, an iSight camera is placed underneath, the computer is coded (it appears, anyway) to look for fingertips pressing through the dye, and just like that, you've got a multitouch interface.
Really incredible. Of course, it's hard to figure out how this could be used for something like the iPhone-- instead of a camera, you'd have to have some kind of light sensors behind the dye, and you'd have to figure out a way to have the dye-colored water stay spread even throughout the bag. In fact, come to think of it, I'm not really sure how most multitouch interfaces work-- maybe this is closer to the real thing than I imagine. Even if not, very cool idea, and I'm almost surprised to see it really works so well.

Update: Looks like the video is a little old-- this was posted back in early June, even before the iPhone was released. But it is still really cool, and it's the first I've seen it.

Cool demo, but it's not really $2 if you need a camera, eh?

Alas, the isight in the imac is built in. But if it weren't I would do this in a heartbeat.

I hope he releases the software for this, maybe even support for cheaper cameras (a $20 webcam wouldn't be a huge additional cost).

Well, I bet it's a lot cheaper than the M$ Coffee Table:

If genuine this is certainly very smart indeed. The programing is the hard part.
I see nothing wrong with it being published in June. You must remember that MutiTouch is not an Apple invention. It came out of MIT I think, any way this video has been around for over a year.

For $2, I think this is very impressive.

This DIY guide is really good, tells how multitouch works, and even tells you how do build your own, with opensource software, that the develper is willing to give out.
