Has anyone been following the developments of supershapes that
appeared in a brief article in Nature as little while ago? Well
3D versions can be made and there are some examples here
    http://astronomy.swin.edu.au/~pbourke/surfaces/supershape3d/
along with a PovRay macro. 

Oh yeah, some people call it a "super formula".

ps: I've never written a macro before so if there are any 
conventions I should have used then please let me know.
