Next time you are driving down the road you might have to turn down the stereo in order to listen to the soundtrack. Some engineers at the Hokkaido Industrial Research Institute in Japan have developed “Melody Roads” that use cars as tuning forks to play music as they pass over them. The concept uses grooves that are cut into the cement at specific intervals in the road surface. Playing off the regular sounds you hear when driving over a speed bump, the grooves are cut in such a way that driving over them creates an audible note. Now, if we can just figure out how to hook up “Rock Band” to this?
