If you’re familiar with Illusion Lab’s Touchgrind for iPhone and iPod Touch, you’ll know what it makes good use of the iPhone’s multitouch capabilities. Today, the developers has posted a video (as shown above) that shows off Touchgrind being played on a MacBook with its glass multitouch trackpad.

The game works just like on the iPhone version. You use multiple fingers to control a skateboard in a somewhat open environment. The game is currently a “tech demo”, but expect to hear more information on it very soon.
