I just saw this really cool invention. When people think of superpowers, invisibility is usually among the first 3 spots so no wonder it got chosen as one of the coolest invention of 2003.
Now, the thing doesnt make you go invisible, but it does make you look transparent. Thats a good start. I believe that sometime in the future, itll be possible to go completely invisible. Its a long way before technology actually allows us so, but of all the problems with the current model, none of them are impossible to solve. If only they can improve the resolution of the image projected, project the image in such a way that the deformations of the suit are cancelled, project the image as an hologram so that it can make you look invisible from any angle and project the image from within the coat so that you dont have to constantly carry a projector around, youll have your fully working invisible coat!
