I've recently become interested in ray-tracing again. I say "again" because I first started playing with ray-tracers as part of a 1st Year Computer Science project when I wrote the Hydrogen Orbitals Renderer. But this time, I haven't been writing my own specialised ray-tracer, I've been using Persistence of Vision Ray-Tracer, better known as POV-Ray.

So other than an interesting diversion and an expression of my inner geekdom, what is this about? I've been making pretty pictures of molecules this time.

What have I got to show at the moment...

• How to render molecules
• The RAFT agent PPPDTA
• (Growing) Gallery of Pictures
