This past June at WWDC, we sat down with the folks from Illusion Labs to dish on all things Touchgrind�[$4.99] related, and the team revealed to me that their original iOS mega hit�would be coming to the Mac App Store this Summer. Illusion Labs showcased a proof-of-concept video in January of 2010 showing Touchgrind being played on a MacBook Pro using the multi-touch trackpad, which led to our speculation that the game would come to the Mac with the announcement of the Mac App Store last October.

It may have taken a while, but Touchgrind has indeed launched in the Mac App Store, and it's currently completely free. The game controls well with the multi-touch trackpad, though it definitely feels different than the iOS touch screen and does take some getting used to. The view is nice and zoomed out, similar to the iPad version Touchgrind HD [$7.99], which makes it a whole lot easier to tell where you are going while cruising around the skatepark.

If you're a trackpad-equipped Mac owner, there's really no reason not to head on over to the Mac App Store and grab Touchgrind while it's free.
