you could do it with lasers, using lasers to draw directly on the retina. I don't think there would be any way to do this with a pixelarray type screen.. maybe

you could do it with lasers, using lasers to draw directly on the retina. I don't think there would be any way to do this with a pixelarray type screen.. maybe if you could map each pixel to a point on your retina and then modify the rendering .. maybe. the concept reminds me of a generative art piece that Kyle McDonald built: https://www.fastcompany.com/90167836/disco-meets-computer-vision-in-this-stunning-light-show https://www.fastcompany.com/90167836/disco-meets-computer-vi... Essentially pile up a bunch of mirrorballs. Point projectors at it. Then map where each pixel from each projector ends up on the walls/ceiling/floors.
