This is some really cool stuff. And considering all the recent ‘gesture user interface’ patents that Apple has files, you can see how great this could work on a video touch screen iPod. 
A standard touch screen only allows one input at a time - this video shows someone with their hands all over the screen, interacting with all 10 digits at the same time!

sweets! that is very awesome! Also, that first tech demo is ridiculously similar to my screensaver (that ATI Flowsaver one…) I wonder if it’s the same thing with maybe some interactivity happening or something… Either way I want one!!
