So this apparently went down back in October, but I just saw this commercial last night. Honda took a section of road in Lancaster, California and paved it with grooves so that when you drive over it, the William Tell Overture plays. The overall effect is quite cool. It reminds me a bit of the fantastic Machine and Acapella spots W+K London did for Honda a couple years ago. Though the project got some bad press with neighbors sick of hearing the noise from passing cars, most people driving over the piece of road thoroughly enjoy it. I almost think of it as environmental art in a way. Check out the commercial to see how they did it and hear the final product.
