Press 'S' to draw the next iteration. WARNING: Don't push it!!! - stop after 8 x 'S' or you machine might overheat!!! ;-) (that's 8x'S' = 9841 triangles - next is 9x'S'=29524 then 10x'S'=88573 then 11x'S'=265720 ...)
Preparing for the ultimate sphere I came across (by coincidence) a technique on how to draw a Sierpinski triangle.
