Andy, The resolution is sure good for a cell phone! In the time the shutter opens and closes could the prop (probably three blades) turn fast enough to give the strobe effect? Or, do cell cameras not have mechanical shutters?? Maybe something to do with the sensor array pattern and the morie effect? I may have seen an odd rendering similar to this of an interference-like pattern in a digicam image. Maybe a clue here: http://en.wikipedia.org/wiki/Interference Alternate theory - I know all about theoretical physics because I used to sleep outside a lot under the stars while moose hunting. Indeed, I shot a moose in my pajamas once... . How it got in my pajamas I'll never know! It is the rip in the Space/Time Continuum somewhere over Alaska. There is a worm hole where strange people appear. AZ Build a 120/35mm Lookaround! The Lookaround Book.
