One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

I have a company in the U.K., a performance-capture studio. We're looking to push the boundaries of performance-capture technology in film and video games, but also in live theater, using real-time performance capture with actors onstage, and combining that with holographic imagery.
