Space Repo Man where you repossess items - in space! It's got physics and explosions and everything. I don't know if it would ever have been finished without this site, pretty much every problem I ran into had an answer here :)
Main interests are physics, shader programming and AI
I have made a simple dice roller for WP7 in order to learn physics engine programming which was quite a time consuming project :)
I am now working on a 2D physicsbased flying game for WP7 using Farseer physics.
Some of my experiments etc are displayed on youtube: http://www.youtube.com/user/mikhog?feature=mhee
