I was just watching Fight Club last night and the 'dude' who makes soap (well sorta, you have to see the movie to get why :P) was explain how mixing soap and kerosense could make napalm :P!
The only things it really needs is bug fixes and one other thing: a button to go frame by frame when the simulation is paused.
EDIT: Something I feel is really important, I think we need to change one of the metals to block charge from NSCN (I was thinking insul wire) cause nothing except PSCN blocks NSCN, and PSCN is too reactive to put into some contraptions (pscn transfers to just about everything)
Also I think it's important that the PTCT should be fixed so that it transfers one-way to NSCN, and PSCN transfers one-way to it, opposite to how NTCT works (PSCN > NTCT > NSCN) and (NSCN > PTCT > PSCN) is how it should be I believe
