This is really interesting:

Any idea how it was done? Watching other videos it seems to be total of 110W laser power. I can't see clearly, but it seems to be 1 laser projector with two mirrors for each beam. Isn't a whole laser projector expensive for such project if you're just projecting single beams from each? The rest of the unused diodes, electronics and scanners in each seem like a waste of money.
And isn't that much power an overkill, even for sky projecting?
Video mapping is more of my thing, but I'm going to try to propose a similar project to a company in my local town. We only need the beams to reach around 5 km compared to the claimed 56 in that video. How much power do you think we'll need at a darker night than in that video?
