The Fractal Tetrahedron
applet no run

An animation of plate 143 in Mandelbrot's "The Fractal Geometry of Nature". Each tetrahedron is replaced with 4 small tetrahedrons in each vertex.
The idea is old a plate in "Polyhedra" by Peter R. Cromwell has an example from 1568.
To avoid a complex figure taking too long to draw the highest level is 4. Rotations are best done on levels 1 or 2.
A correspondent tells me that my fractal tetrahedron is called the Sierpinski gasket.
Sierpinski gaskets with 16 cells make excellent kites.

a really good set of plans to make a Sierpinski kite with drinking straws ,It works I have tried it.
