"Celfuuu is an in-browser tool to create 3D models, then export them as a .dae collada file. Then you can load them in like blender/ sketchup, Secondlife / opensim grids, print them out in 3D. etc."

This runs on the web and makes strange spiral shapes and pulsating rings. I haven't found a use for it, yet. Go to http://celfuuu.pixel-lab.org/ to check it out.
