Next, we’ll be able to paint it on a building
Truth. But the real deal is AR.
It’s coming sooner than we think.
I thought I had read awhile ago (years) of a paint that had some sort of thing in it and you could flip a switch and have it change colors.
Found it - “nano paint”. Uses an EM field to polarize the molecules somehow to different orientations for different colors. I imagine a TV paint is doable - if not already done.
