Merely concept right now, but someone wants to design this bad boy to make your dry protection into a musical medley. From the site:

I like the idea behind this Rain Drum umbrella that turns the pitter patter of raindrops into various drumkit sounds. It uses five wax cloth ’shades’ that each have a different elasticity to produce unique drum sounds as the raindrops bounce off of them. Of course the stiff frame needed to keep the drum skins taut doesn’t look like it folds down that easy, or at all, and the irregular shape of the umbrella as a whole could actually make it kind of tricky to stay dry. But, you can’t fault designer Dong Min Park for his concept that basically tries to create a silver lining for a cloudy, rainy day.
