Rain Drum, a recent work from a South Korea-based designer Dong Min Park, has been very popular on the Internet, and deemed as “an interesting amusement for boring rainy days”. The shade of the umbrella is made up of five different wax cloths, to imitate the different frequency of the hi-hat, crash, tom-tom, bass and snare. So next time you’re in the rain with such an umbrella, you’ll surely experience something new and enjoyable.
