If you like this, maybe you also like this Path Tracer written in 99 lines of C++:

Thanks for sharing this. Especially on the page there is a presentation as well as several ports of this same program to other languages like OCaml, Haskell and JavaScript. Interesting to see that the OCaml version is on par with the C++ version performance wise, but is 47% shorter. However the Haskell version is not shorter and 4.5 times slower?

And here's a comparison between that (smallpt) and the equivalent (smallptGPU) using a GPU:

All VERY interesting stuff.

And if you like that (spheres only), you might also like this (general triangles-based), in 444 lines of Scala (and OCaml, Python, Ruby, Lua, Scheme, C++, and C):

All this reminds me of Paul Heckbert's ray tracer written on the back of his business card: http://www.cs.cmu.edu/~ph/src/minray/minray.card.c
