Interactive fractal polyhedra

Sierpinsky tetrahedron and fractal "bitetrahedron"

Controls: Drag mouse to rotate objects. Press mouse with "Alt" ("Ctrl") to get the next (previous) iteration. I would improve this Java 1.1 applet if I could draw an image with trancparent background. See Hidden Surface Removal Algorithms for explanations.

Fractal octahedron and cube.

Thanks to Rich, I've added Ron Resch and Menger's cubic sponges (click mouse to see how to make them). The first fractal is really Sierpinsky tetrahedron made of small cubes and Menger is too "heavy" for the third iteration :)
