Projection mapping - this has been done with buildings and other rigid structures with great results. Bot & Dolly did this great video six years ago. They were assimilated into the Google collective in 2013 - I hope for a lot of money.
Now, combining high-speed computer vision, it is possible to warp the projected image to match the deformations of the screen allowing projection mapping on a flexible surface.
From Hackaday:
A group in the Ishikawa Watanabe lab at the University of Tokyo has a technique where they cover the target with a number of dots in an ink that is only visible in the infra-red. A high-speed (1000 FPS!) camera and some very fast image processing then work out not only how the surface is deforming, but which surface it is. This enables them to swap out pieces of paper and get the projections onto them in real time.
The video is amazing - I can only imagine when some real artists get hold of it:
