Sierpinski Pyramid (Q46644)

This is a 4-sided sierpinski pyramid, a 3D representation of a sierpinski triangle[1]. Probably not printable, although the inverse might be... Unfortunately, there isn't too much detail in these renderings because my laptop crapped out rendering anything over 4 iterations. NOTE: openscadpy[2] is needed to use this .scad file. This thing uses a recursive function which is not possible with openscad [1] http://en.wikipedia.org/wiki/Sierpinski_triangle [2] https://github.com/hmeyer/openscadpy
