Just one question:
  What's the difference between making a series of rotations, scales and
translates in your program or in povray?

  Well, parsing a matrix may take a couple of milliseconds less than parsing
10 transformations, but does that matter?

  Note: I'm not saying that your program is not good. It sounds like fun.

main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):_;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/
