What about poison gas or something? It could kill the stickman (not instantly though) and eat through plants. Also, plants should be tweaked so it doesn't act like green ice in water.
Hopefully this doesn't get lost in all the nonsense posts:
My suggestion is to add a fourth noninteracting electronic element, to complement PTCT/NTCT/METL. The purpose would be to allow more compact cabling, as demonstrated in the image below.
Top, middle: Currently possible wiring methods for an 8-channel signal (there are others, but none smaller) Bottom: My proposal, with VOID standing in for the new element. Note the two-pixel reduction in size.
The new element would not interact with PTCT, NTCT, or METL. It would interact with PSCN and NSCN. If it can be given other functions without impairing the suggested one, all the better, but the main idea is to reduce the size of data-carrying cables.
um3k hmm... this does tie in with my idea of a super conductor, although i didn't propose that it wouldn't conduct with other elements in the electronics section. My idea would be to have an element that would conduct electricity instantaneously, like an activated switch.
1# Solid Stone and/or Solid Concrete Description: A solid that is strong enought to withstand some heat and preasure (unlike Glass) but does not conduct (unlike Metal). It shall be meltable and become Stone/Concrete dust under to much preasure (200+ or such, so a lot!). As usual concrete could be the "stronger" variant of stone. Use (kinda obvious, gonna list some though): -To much preasure and heat could destroy your Creation, there are no indestructible "Walls" in reality: Imagine a Nuclear powerplant where you got to keep everythign controlled or your walls would breake -> Chernobyl -For constructions that are supposed to collapse: Nuke Bunkers and Bomb testing.
2# Heater and Cooler Just like Heat and Cool but as a placable solid that emits heat or cold (emit cold, heh). I am not entirely shure if that works propperly but something like a pot made of "Heater" to boil water that vaporizes to steam and hits a Detector, sounds interesting IMO.
