Spidey (or Gecko-Man)

Ever wanted to climb up walls? Shoot webbing and swing across cityways? Well, new technology may help you climb up walls! It's called Gecko Tape. The Gecko Tape is created with millions of tiny hairs that cling to surfaces. Much like the way Geckos cling to walls!
BBC says this:
The researchers say the material clings so well to a surface that by covering the palm of one hand with the tape, a person could hang from the ceiling - just like the remarkable lizard.

So far, however, Professor Andre Geim and colleagues have only been able to make a very small square of their gecko tape because of the difficulties involved in the fabrication process.

Nonetheless, the University of Manchester scientists are confident they can refine their work so that commercial quantities of the new sticky material can be produced.
