The size of the field, is it fixed or growing? I guess, if it is fixed, this implementation still needs some work... Either way, I think that Turing Machine with infinitely growing stacks [see http://rendell-attic.org/gol/fullutm/index.htm http://rendell-attic.org/gol/fullutm/index.htm] is a way cooler.
