Blender isn't a personal project of mine, but rather an open source 3D animation application to which I have made some minor code contributions. You can download Blender at http://www.blender.org
I wrote the first version of the multi-shader system in Blender, and I am responsible for writing several of the shaders in Blender, including the Blinn and Oren-Nayar shaders. Prior to my work Blender only had a single shader: a modified Phong + Lambert shader.
I also wrote three of the nodes in Blender's node-based shading system: the scalar math node, the vector math node, and the "Camera Info" node.
