I find Zach(tronics)'s take on this in KOHCTPYKTOP much more pleasing somehow.

Of course, it's difficult to play now, since the webpage [1], and steam version relied on flash, and you have to fiddle with a 3rd party flash reimplementation.

But its implementation of semiconductor behaviour is much better than wireworld's.
