[Haskell-cafe] ANN: mecha-0.0.4

Mecha is a little constructive solid modeling language intended for 3D CAD. This release adds animation capabilities, which use POVRay and FFmpeg behind the scenes. At work we've used Mecha to illustrated the kinematics of a new hydraulic pump design -- I wish I could post the animation, it's pretty cool to watch. http://hackage.haskell.org/package/mecha/
