A team from a Hokkaido Industrial Research Institute has made a road surface that plays a song when you drive over it with a certain speed. Depending on the distance between the grooves the car will act as a tuning fork and play a "note" at a certain frequency. The song lasts about 30 seconds and you have to drive over it at a fixed speed of 28mph.
