Organizers of an effort to get UFO reports taken more seriously teased journalists on Friday with glimpses at dark, grainy video showing what appeared to be a face peeping up from a window.

The video was played at a downtown Denver news conference, after days of buildup from a Denver resident who is circulating a petition calling on the city to create an "Extraterrestrial Affairs Commission" to deal with reports of alien encounters. The petition drive's organizer, Jeff Peckman, hopes to get 4,000 signatures to place his initiative on the ballot.
