Ok so i have an idea for a new wall thats sort of programable. you would draw the wall and then chose which element(s) it would block. also there could be one that you choose which element(s) to let throu. i think this will make some things easier to make
Well for example i figured out that if you had water surrounded by iron and you sparked the iron, it changes the water to hydrogen and oxygen. the wall could filter it and only allow the oxygen to go through. can stor do that?
