I could watch this all day.
These vintage cards and old placards display optical illusions, visual witticisms, hidden images, rebuses, and artistic paradoxes from yesteryear. They were the equivalent of Gifs back then — eye candy worth sharing. Here they are gathered in a oversized paperback for your entertainment and amazement.

M.C. Escher: Adventures in Perception (1971) is a 20-minute Dutch documentary about the artist and includes scenes of him working in his studio. From Open Culture:
Obsessed with perspective, geometry, and pattern (Escher described tessellation as “a real mania to which I have become addicted”), his images have, by the count of mathematician and Escher scholar Doris Schattschneider, led so far to eleven separate strands of mathematical and scientific research.
The twenty-minute Adventures in Perception, originally commissioned by the Netherlands’ Ministry of Foreign Affairs, offers in its first half a meditation on the mesmerizing, often impossible world Escher had created with his art to date. Its second half captures Escher in the last years of his life, still at work in his Laren, North Holland studio. It even shows him printing one of the three titular serpents, threaded through a set of elaborately interlocking circles, of his very last print Snakes. He never actually finished Snakes, whose patterns would have continued on to the effect of infinity, and even says here of his officially complete works that none succeed, “because it’s the dream I tried for that can’t be realized.”

My daughter send this photo to me. I put it in Photoshop to check. The "reddest" part I could find using the eyedropper had an RGB value of 153/181/182. So technically there is some red in the image, but here is what 153/181/182 looks like:
Not very red! Read the rest
The guy in the cap doesn't get it, but the smart bald guy in glasses knows how it works. From the Bell Science Series film, "Gateways to the Mind" (1958).

There are twelve black dots in this image. Why can't you see all twelve at the same time?
I replaced the black dots with red dots, and it is easier to see them all at once. Read the rest
He also makes a lot of cool creations involving images of mice and ants.

It took me a while to figure out what the deal is with this photo. I thought at first someone coated their thighs in oil. But then I saw it for what it really was. It reminds me of a Necker cube, only for legs. Read the rest
