// other animations in this thread use the TES system (tessellations/sample/star-*.tes)
// but hexagrams and horospheres are not supported in tes, so we do them manually
// commandline: -canvas 0 -geo 44onh -PM 0 -horo63 -tstep 16 -noplayer -back ffffff
// add to make a animation: -shot-1000 -animrot 1 90 -animvideo 300 name.mp4
