...and I'm fairly sure it is true as long there is proof that the 
iterative calculus is Turing-complete as all Turing-complete calculi are 
idempotent.
But I'm much more interested in the practical aspect and expressing 
recursive raytracing with iterations is trivial in this case as the 
OpenCL kernel-language is close to C99 (just without recursion).
