In this morning's "The Age" newspaper (a Melbourne local paper) there is an article about a bike helmet that is Arduino-controlled:
The helmet is Wouter Walmink's idea.
Apparently it automatically changes colour (like to red when he is stopping) and shows indicator arrows when he is turning.
Based on the video, he's using an LPD8806 LED strip in a creative fashion on a bike helmet. He included a gyroscope/accelerometer (couldn't tell from the video) sensor to change the patterns based on head angle. Very cool. Those strips are very handy when controlled by the Arduinos!
Hes got the brake light back to front .Does he even occasionally ride a bike?
When you brake your head goes forward . So in his video the brake light only shows up when he remembers to tilt his head back

Just a guess here, but usage testing probably showed that tilting the head forward occurred far too often for other reasons to use it as a braking signal. You're more likely to look down at something approaching than you are to look up. Tilting the head back would minimize false brake indications.
