Piano Doorbell Turns the FedEx Guy Into a Virtuoso

Musical doorbells are annoying enough, but what if you gave your visitors the freedom to express themselves creatively? That's exactly what designer Li Jian had in mind when he came up with the Pianobell. Unless you are friends with a lot of talented musicians, I don't see much of an upside here. On the other hand, it could be amusing to torture your FedEx guy with a bizarre form of performance anxiety. Fortunately for him, the Pianobell is only a concept at this point. [Labexp via Freshome]
