copied said88 about proteins, but still good. +1
I was thinking of adding Protons one time, not because of any suggestions at all, but because someone proposed an idea that gave it many uses, and not just "Add PROTons, PROT + ELEC = HYGN". Move tool - I don't completely understand, but it sounds like FRME, which someone suggested. LED's - LCRY?
these all make sense, I would suggest it as a thread on www.powdertoy.co.uk if you want them to be seen by more people +1
