In all honestly i think the whole flubber thing was one big hoax. It would be nice if we could change its colour or even what it displays, but i dont think it will happen. I think this was just a joke on you all by complex.
Hope im wrong, but i doubt i am. I remember when this first came out, it fizzled out shortly after and nothing has ever been said about it by complex since the initial release. Its just everyone else that seems to keep this going.
