Recently my son was enthusiastic about anaglyph images viewed with red-cyan glasses. These are much better than what they had when I was a kid because the cyan filter passes both the green and blue channels. You can use whatever color you like as long as it isn't red or cyan.
I got enthusiastic too.
We found out that you can't (in general) make a good anaglyph image with a 2-d image and a height map because the left eye and the right eye can see around objects so the 2-d image usually is missing pixels that the left and right eye would see.
You could reproject an anime image if you had the cels; you could reproject the image for the left and right eyes by simulating the multiplane camera.
I am just starting to take 3-d photographs by moving my camera and that way I get all the pixels for the left and right eye. That lens might be better for taking portraits at very close range but I don't know if it would beat my current lenses. Certainly I could get a really good telephoto lens for that price today whereas I don't even know if I'll be taking 3-d photos a year from now when that lens would arrive.
