This is actually one of my childhood dreams. Having some kind of sticky stuff which would allow me to climb on walls (and ceilings maybe), but already I knew the problem as far as I understood. If I could stick in the wall, how could I be able to move?

Of course there could be some ways to do this actually, as animals are able to do this, but you can't blame a kid for now knowing everything.

Nowadays I just don't have as much interest in climbing around the walls, as sad as it is.
