DoorJamz Is A Doorbell With Custom Tones You Can Control With Your Smartphone

I have two problems with doorbells. First, they sound incredibly annoying. Secondly, there isn't an easy way to turn them off. DoorJamz provides a solution for both of these problems. It's still a doorbell, but instead of the consistently infuriating "ding-dong", you can choose to have it play whatever you like. If can have Led Zeppelin's Kashmir play whenever your guests or the Jehovah Witnesses announce their presence. That's pretty cool.
