The Blackbird,Fly is a 35mm twin reflex camera by PowerShovel/Superheadz of Japan. Powershovel designs toy cameras, these are not reproduced from some old Soviet plans or found in a warehouse somewhere. You can pickup one of these toy cameras in various specialty shops around the US or by mailorder. It takes pretty cool pictures, a BBF Flickr Group has a lot of examples of the results. I love that it uses regular old 35mm film and the exposure frame overlaps the sprockets.
