Flower of life design made with [Antiprism](http://www.antiprism.com).
Here are the commands
polygon dih 60 -r 1 | off_util -s > circ.off
off_trans -T 0,0,0 circ.off | off_color -v E -e red > c0.off
off_trans -T 1,0,0 circ.off | off_color -v E -e black > c1.off
off_trans -T -1,0,0 circ.off | off_color -v E -e white > c2.off
off_util c0.off c1.off c2.off | off_trans -Y O,C3 | poly_kscope -s O | antiview -v 0.03 -e 0.03
The first one creates a polygon to use as the circle. The next three
commands make coloured copies, so you have a red, back and white
circle in a line. The last command combines the circles, aligns them
with the hexagon of a naturally aligned cubucotahedron, and then
repeates them to have octahedral symmetry.
