Japanese researchers have built a robot that balances on a ball. It's wicked cool, like a Segway taken to the next level. It is really amazing to me the extent to (and speed with) which science fiction from the 1960's has become reality. Today we have Star Trek communicators (cell phones, blue tooth headsets), tricorders (PDA's) and now we seem to be one voice synthesis circuit and some molded plastic away from Rosie Jetson. Still waiting for my hand-held phaser though.
