Created Biscuit 3D software suite. Was a lua/python scriptable C++ 3D library with OpenGL preview with a Node based interface which ran in a PRMan procedural DSO for rendered output.

Node based 2D image editing software written in C with GTK (ick).

Other random software like tree/forest generator, Cloud raymarcher, flame fractal generator, wikipedia visualizer, procedural terrain generator.

Non photorealistic rendering system and Animation.

FX and comp work on group animation project 'The Obvious Threat (to untold number of citizens)' was featured on the channel frederator animation podcast.

Lighting, FX and Environment work on group animation project ' least I'm alive... ', the characters currently being developed into a children animation series I hear.
