Ahh amazing, thank you! I went searching for other videos but couldn’t find any. Somehow didn’t occur to me that the objects on the ceiling in OP’s video, with the exception of the speakers, were images on a video wall too :). Explains the weird way it looks!
Interesting! The university I attended had a similar room using projectors, but it was never as impressive as this. They did have it rigged to play Doom, though!
