Singing Streets

A bit of bizarre news caught my attention recently and it got me thinking. It was about these roads in Japan that had been designed to play music as cars drive over them. The engineers behind this idea cut thousands of grooves into the roadway, separated them by certain specific intervals, and then drove their cars. What resulted is a weird humming melody that reverberates in the cars as they drive. The video linked below showing the roads and their songs is awesome, but so much more could be done.
