I was hit by a car on my motorcycle a back in October 2010 (rear ended while I was stopped in traffic), so once I was able to function as a human being I spent the next 2 months of disability learning Box2D. My first thought for a project was, of course, to recreate my accident as a physics-based game 
  This is my first go at it.  Granted, it’s buggy and very simple, but it’s a proof of concept more than anything:

All aspects are authentic…the dude is me, same outfit, same motorcycle (R.I.P., 1971 mint condition CB 350 :(, same car that hit me, etc.  The only exception being that there was no skateboard ramp involved 
Feedback welcome!  This is merely a first attempt.  Bigger things to come hopefully
