Nice demo of this functionality. Its nice to see a reasonably priced video projector being able to emulate the beams. I know when I tried this ~4-5 years ago using video recordings of shows, the relatively poor contrast ratios on my video projectors significantly diminished the effect. That Epson has a contrast ratio of "up to 320,000:1". Wow!
From a set-up perspective, it would be even more convincing the projector output was physically closer to the laser projector. Some nice "seamless" transitions between laser down to the video projector zone would also help convince the audience they were being scanned. In any case, it looks like this has the capability to look better than transitioning to a safety scan lens - especially when using one of the higher power safety scan lenses.
