I started playing around with more VR/AR based stuff, and one thing I think would be cool is if windows would blend in with reality. That is, react to light sources, to determine stuff like shadows and gradient angles. Ideally, I would use real data from either a camera or some other sensor to calculate the position of the light source(s) in the screen, but being a prototype, this was just to see if I liked the idea in a simple scenario. Any feedback or criticism is appreciated. And of course, I will release the prototype if people are interested.
