you are right, IORef is appropriate only for single-threaded

I have recently posted a haskell port of my ocaml raytracer, Glome:

It supports spheres and triangles as base primitives, and is able to
parse files in the NFF format used by the standard procedural database
(http://tog.acm.org/resources/SPD/). It uses a
