Twitter+RFID Equals One Futuristic Cat Door
Although it may not look like much in its raw form, the Twittering cat door is an impressive piece of hi-tech house modification. A computer programmer has hooked up his cat's entryway with an RFID sensor that sets off a chain of automated events when either of his cats come near. The door will only open for the resident cats, Gus and Penny, who have special RFID collar tags, and when they enter a Tweet is sent, and a photo is taken. The hack has been very successful in keeping out the neighborhood cats who were eating Gus and Penny's food.
