Lights

Look very similar to the Aura Lighting System.

Also, I went to a product design exhibition in Berlin this summer, and there was a bike which had LEDs set into the handlebars and seat tube. It looked pretty good, though the obvious concerns would be bartape and what happens if the circuitry fucks up. You'll need to dismantle your bike for a couple of lights.

Again pretty cool, but i think (looking at the video's of the two lighting systems) the difference between the two is the revo system projects the lights forward and backward on onto the grounds wheras the Aura system doesn't seem to be able to be seen from the front or back, only the side.
