how about nnob? (nanobot) behaves like tron,but inside material's,and if you click on it with a stamp it will "save" that stamp and once it hits the materials the stamp is using it takes them and starts making the stamp. has the same colisions as proton's,moves like tron. it's probably way to much work for something like that tho,so I suggest to ad some additional functions,Wich I don't have any idea what they could be at the moment.
ALSO can you add powered portals
