When writing software for fun, what better target than a game. I am currently working on several projects, but coming soon is a 3d Craps game.  I hope to have Casino Craps release later this year!  It is a Craps game simulation built on the Unity game engine. I use Unity for the game development, Blender for the model development, and Gimp and Inkscape for the art assets. It has been an incredibly fun project and required that really dig into 3d modeling.
