This isn't, strictly speaking, a hoax, because I'm quite sure that its creators are serious about it. It's a UFO Attracting Device "equipped with colored strobe lights, low-powered lasers, a radio transmitter and a series of gauges said to track atmospheric changes common to extraterrestrial encounters."
It was originally built by Myron 'Mike' Muckerheide, but was then purchased by Julie 'Jitterbug' Pearce. I would definitely buy this thing, if given a chance. But instead of using it to attract UFOs, I'd use it to drive my neighbors crazy. Whenever they play their music too loud, I'd crank up my UFO Attractor and drown them out. If a UFO happened to land in their backyard as a consequence, all the better. (via The Anomalist
