Alright, so I finally looked into 2d Physics. This engine is faar from perfect, but I'm still very happy having done this program in just one weekend, damn I love C# .net! (Although I have done some additional tweaking during the week, but my job goes first I'm afraid). 
Link to file it needs the .NET 2.0 framework. There's no friction, there is jittering, and I need a bias impulse to uncollide bodies. I wanna thank Erin Catto for his amazing Box2D demo (google!) and Chris Hecker for his great articles! When this engine is perfect I might do something like The Increadible Machine, that would be cool. Anyway, the program is quite self explaining. Keep the physics "Stop"ed and add boxes with infinite mass to keep them still (For example ground). And to begin I'd recommend adding two boxes, then choose "Apply Force" this is a pull-force, so drag a line from where you wanna apply the force. It can also crash, please don't give me the bug rapports (And it crashes user friendly, by throwing an exception, so don't you worry). Have fun! And please comment! /MindWipe EDIT: Bias Velocity added! w00t! Havn't had time to tweak it though, but works! :) [Edited by - MindWipe on August 2, 2006 6:18:01 AM]
