Revisited my old DD to see if it would be a nice base for the
mandelbulb3dteasers.
This image actually features IcosahedronIFS + ABoxMod4d. The latter however refused to mix or interact with IcosahedronIFS - it's just a black bar outside of the image view

To make something new from the icosahedron I made it a mesh at
Shapeways. What a pity that we can't export with colors yet! So the mesh prints out as white plastic material.
