Actually, there are at least two ray tracing apps. One I wrote myself which didn't get any further than planes and spheres. And one was a basic app from Japanese origin which was somewhat more capable and use screen12 for output. Naturally, it was dead slow 
Spheres are for atoms, atoms are for molecules, molecules are for all kinda objects.. so basically all you need are spheres! (And oodles^oodles o' memory )
wolf_: can you give me the proof that atoms are spheres?
sjoerd: did you already get the prize for MSXDev?
PS: your site is quite fun 
Please upload the rest, so that it will be even more fun

More Easy that make a simple 8 frames animation in a PC and convert to MSX format?
