Hi Brian,

interesting read. I attach for you a Peano Gosper Curve with more iterations. Maybe you find it useful. It is done with Shade3D vers. 12 and a preset from Mr Toshiaki Katoh's Math Modeler, which you would probably love... (unfortunately OS X only).

If you want to take a look what his Math plug-in's for Shade3D can do:

it is under the Scripts section and the first link is for the videos.

Best Regards
Stefan
