Yeah the game for the computer is really addicting and fun.

Some people get wayyy to caught up in it though:

YouTube - Line Rider - Transcendental™ by TechDawg
YouTube - LineRider "Discarded" A Line Rider Short by TechDawg
YouTube - Line Rider - Movie Mania [Improved Version]

I can imagine how this would be hard to do on an iPhone.
