I'm here to help build the project, and generally get others involved. I've been using SketchUp on and off for about 5 years, and I've been using SketchyPhysics for almost 2; I virtually never build anything other than SP models any more. I enjoy playing games, and I've recently become interested in making them; have a look at this to see what I mean.
Thanks to everyone that's gotten involved in the project, and Sgal93, who started the Wiki. Also big thanks to Chris Phillips, the creator of SP, and the guys behind Newton Game Dynamics, who made the engine SP uses.
