Why keep all of your geeky gadgets indoors? You might as well show your geek pride outdoors as well. With this alien doorbell, there will be no mistaking just what kind of person resides within the house. When you press on the alien it will interchange between a few different sounds that play through the UFO shaped speaker. Like the sound of a landing aircraft, the words ‘We come in peace’ or ‘Greetings earthling’. To pick one up it will cost you £15.99 or about $25.
