@david @codinghorror I know...
The closest to that I could do is "pliseé-prints" where it's effect is less fluid and one can obviously see the two options.
@kkarhan I had to look that one up!

Back in the day I had a whole bunch of posters like this of Lenin, but Soviet realism did a much better job of posters, at least.

@codinghorror "Lenticular stickers which change from an image of Donald Trump with the text Make America Great Again to a zombie surrounded by Obey and Make Billionaires Even Richer" would be better alt text! "An assortment of lenticular stickers on a kitchen table" is true but rather misses the point.
Also, TIL that those things are called Lenticular :)
