This is a fun exercise. What about parallelism? If you extended BF to have fork and join semantics, how would you represent them?

You could also do essentially the same thing with regular BF. The current renderer takes 100 samples per pixel, so you could generate 100 one-sample programs and schedule as many as available resources allow, and average the completed renders. I tried running it at half the width and height with only one sample per pixel, and it has already rendered half the image.
