What I read from the news today... Japan melody roads play music as you drive.
A team from the Hokkaido Industrial Research Institute has built a number of "melody roads", which use cars as tuning forks to play music as they travel. The concept works by using grooves, which are cut at very specific intervals in the road surface. Just as travelling over small speed bumps or road markings can emit a rumbling tone throughout a vehicle, the melody road uses the spaces between to create different notes.
Melody Roads are located in the provinces of Hokkaido, Wakayama and Gunma, and are well-marked by roadside signs and colorful painted "notes" on the roadbed itself. The optimum musical speed being 28mph in your car.
Sounds interesting right? How good if Malaysia also have melody road like this!
