A really good example of projection mapping at home.

If I had more spare cash, I would love to get a powerhouse projector and get into this shizzle.

Very impressive, presumably that software is quite nifty given the massive task of working out to which projector the stuff needs to go.

i think there are both expensive auto scanning software and cheaper manual input softwares out there, but, looking at the scale of this example, I'd go with the former. I need to research more and see if I could achieve similar on a realistic budget

Alright if you do light and sound for a job but it looks expensive for something to get bored of

I think if you have a decent laptop then you only require a decent projector, but by decent, you'd probably need to spend a couple of grand, or at least from what I've seen / read.

Is that just one projector? I thought it may be a few perpendicular to each other. Either way, some hefty maths going on.

Quite possibly, it's difficult to figure out from the video.

Looks it to me or its a very high contrast to get the surfaces that bright at an oblique angle.

Most of the time it's static so the environment is modeled and the animation is laid on top of that (using mapping or post-prod software, Millumin etc). Then it's a case of correctly aligning the projector(s) to the (real world) environment and playing static footage.
Multi-projection setups (for big environments, rather than double-stacking) is a bit more difficult but the modeled environment will help with projector placement and/or there's software that'll handle that aspect.
Major cost is the projectors, especially if you want to do outdoor mapping.

Only reason i know a little about this is because i was attempting to do it back at uni; didn't get particularly far as there wasn't really one-stop tools/software back then, plus i was attempting to use MaxMSP and go down the interactive route (with enough time i probably could have got somewhere with it).

Interactive or reactive (like this - https://www.youtube.com/watch?v=SE1A0Ll9omc) projection mapping is where it get's interesting though but it's pretty bespoke at that end.

That pool one would be cooler if you got the lines like when you used to play it in Flash.
