There's a Piano Doorbell That Lets Your Guests Make a Tune

The Piano Door Bell lets your guests tickle the ivories with a new tune every time they come over. The piano doorbell is a concept that was designed by a Chinese designer named Jianye Li. But In reality does anyone actually use doorbells anymore? Now-a-days friends just walk in when they arrive, the only people who actually ring my doorbell anymore are selling me garbage cans, candy bars and magazine subscriptions.

Consider me a customer the second this product comes to fruition. Someone please kick start a kickstarter for the piano door bell immediately.
