Here a few organic molecules and crystal structures drawn with the POV ray-tracing tool. The "building blocks" (atoms) are simple, but the arrangement in space of the bigger compounds is not straightforward. I had to review my geometry and trigonometry. And just in case you didn't guess, I am a chemist...

= H,
= O,
= N,
= Cl,

= Metal.
