Inhabitat recently reported on Boyan Slat, a 19-year-old student who designed an ocean cleanup array that he estimates could remove 7.25 million tons of plastic from the world's oceans.
It all began with a gust powerful enough to blow a large slat of wood loose from a construction site and send it hurling into a storefront with a slam, spraying shattered glass everywhere.
Under each wooden slat, a resonator made out of calabashes is fastened, tightly sealed with beeswax, and tempered with the oil of the nkuso fruit, giving the timbila their rich nasal sound and characteristic vibrations.
