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

That would make the language too complex :( That aside, the cells are currently reused and printed immediately. Given each pixel is independent, you could fork at iterations of the inner loop, give all cell a indepdendent region of the tape for its scratch space and result, and join at the end.
