Your REPL GOL is awesomeness, but uhh... It's still twice as long as mine >_>;; You made the barrel twice as long to make it capable of heating twice as many photons, but that kind of defeats the point. It's not smaller if you have to make it twice as long to keep them hot. :P
@andrewdavidloftus The same way yours does. PCLN has the fastest conduct speed, similar to FILT and normal clone, and metal for example.
btw, I just thought I'd add this in. My original laser is actually 470 parts. The extra 300 is the shielded ball of metal I added on to give newbs an easier way to switch it on.
