The app from Humanoid called Super Shred Bros. is out now for iPhone. I just downloaded it and it seems pretty sweet. Allows you to view a sequence of a trick and then take a video of yourself doing it. Allows you to collect points, up your "level" and access more advanced tricks. Pretty nifty.
And if you download it, check out the toeside indy grab sequence and see if you recognize the rider
(sorry, I was pretty stoked to see myself in an app)
