RIM has released a new title for the BlackBerry PlayBook called TunnelTilt. It’s a fun and simple little game where you tilt the PlayBook around to move the small, glowing orb through the tunnel. There are walls along the way that you have to maneuver your orb around in order to keep rolling. The game also features a pretty cool soundtrack. This game is not just a pretty time-waster, though. It’s actually a proof-of-concept for the ultra-smooth 3D WebGL that the PlayBook can run. This is a demo for consumers to see the power of 3D WebGL and for developers to get motivated to use this technology in their PlayBook applications. You can grab the game for free at the link below.
