At one point, mostly due to the Master's work of Miranda, I became interested in shape grammars. I wrote a little program called xform3d that allows a user to dynamically manipulate 3D shape grammars; kind of a less elegant, hard to use version of Miranda's program, Shaper2D. Below are a few of the nice images to come out of early versions of xform3d
