Ask your little sister to make all the tetrahedron beams... and concentrate on the assembly. Just before you throw it in the bin watch this vid ... and have another try!! No money back guarantee... http://www.merrimack.edu/~thull/fit.html

A re-render of the Sierpinski tetrahedron. This time using a much better rendering algorithm (17* faster *and* also more accurate).

For all those who like a challenge! This is an extremely complicated model to assemble so do pay careful attention to the still pictures when they come up. This would take aproximetely 2 hours to complete, but it looks fantastic at the end. Good luck! Tell me if you have any trouble or want any tips and I'll try and help out.

This continuous loop rotates around a nest of the five Platonic Solids: Cube (red), Tetrahedron (yellow), Octahedron (green), Icosahedron (blue) and Dodecahedron (purple), returning to a cube oriented along the same x-y-z axes one third the size in each dimension as the outer cube. The transparency of the inner cube.... more

The basic shape splits into two and the cube is outlined
