This is only slightly Mac-related but it is really cool. We've posted about two of Illusion Labs' popular iPhone games here on the site: Touchgrind is a 3D simulation of a touchboard, and Sway is a really fun little platformer-esque swingathon that has you swinging from side-to-side using the touchscreen. Both games are pretty original in how they use multitouch controls, and so when Illusion Labs got their hands on a big tabletop touchscreen, there was only one thing to do: blow the games up and play them in a big way.

You can see how it looks above -- seems like a lot of fun. And it makes you think, too -- multitouch seems to be where its at for the future of user interfaces, and the iPhone is really a breeding ground for testing out the technology and coming up with new ways to use it. It may be a long time before we all have huge multitouch screens like this in our kitches and living rooms, but considering how ubiquitous the iPhone already is (and the fact that almost anyone with some time, $100, and an idea can publish an app on the App Store), we can start seeing the kinds of applications that will live on those screens right now.
