did you know that the default Windows 10 desktop background is a photo, not a digital effect?
it's a Kvant Spectrum laser projector with Saturn 9000 scanners beaming light into a sheet of transparent acrylic with black cardboard masks.
there's even a short video showing an animated show variant of it here: https://www.precisionlasers.com/projects/windows10
