It's impossible to project beams that way! Light travels in a straight line. You're not going to bend it in air like that. (Well, unless you've got a pocket-sized black hole hanging in front of the projector!)
I've seen the same sort of image distortion when shooting video with my FLIP camera. (Yeah, it's cheap, but it gets the job done when I'm in a hurry.) However, I do not see those artifacts when I use either my hi-8 camcorder or my digital camera to shoot laser video.
Bottom line - it's an artifact of the camera. It doesn't look that way in real life.
