I was more impressed with this: http://toucharcade.com/2009/04/06/illusionlabs-sway-and-touchgrind-on-a-massive-multi-touch-table/ Touchgrind on a Macbook still seemed to be zoomed in too far for me, but it's probably because it was only a quick tech demo.
Well, it's possible to distribute Touchgrind and give it lots of attention if it's running on a MacBook. Imagine the whole (MacBook) world downloading and playing this!
