Do you remember having a Rubik’s cube?. I think everyone more or less had one at some point. They were all the rage.
Blue Storm Spirit from Deviant art has quite cleverly made this ordinary Rubik’s cube into a Tardis one from Doctor Who. Apparently it’s made with a variety of stickers and even glows in the dark. Unfortunately it can’t warp you to anywhere else, but it is kind of fancy looking.
