Jesus turns his head to watch you on this gravestone

The hollow-face illusion is put to good effect here.

From Wikipedia:

The Hollow-Face illusion (also known as Hollow-Mask illusion) is an optical illusion in which the perception of a concave mask of a face appears as a normal convex face.

While a convex face will appear to look in a single direction, and the gaze of a flat face, such as the Lord Kitchener Wants You poster, can appear to track a moving viewer, a hollow face can appear to move its eyes faster than the viewer: looking forward when the viewer is directly ahead, but looking at an extreme angle when the viewer is only at a moderate angle.

Is the hollow-face illusion not working for you? Again, from Wikipedia: The Hollow-Face illusion is weaker among people with schizophrenia and other populations with psychotic symptoms perhaps as a result of reduced tendency to interpret any kind of ambiguous 3D object as convex. It appears to be related to current mental state, namely in regard to current positive symptoms, inappropriate affect, and need for structure. The illusion seems to strengthen among successfully treated patients.

The Coffer Illusion - how many circles do you see?

Relatively interesting has three good optical illusions in this post. My favorite is the Coffer Illusion, which was a Top 10 finalist in the 2006 Best Illusion of the Year Contest, but is new to me. Do to see all 16 circles? For me, it took a while. Read the rest

This video explains why craters sometimes look like hills in photographs

The sun lights things from above, so our brains are used to seeing shadows appear below convex things and above concave things. It's easy to trick your brain by rotating a map or photo upside down. Read the rest

Cat goes ape for this 2-D optical illusion

Humans aren't the only animals affected by trippy optical illusions, as Ryan Kotzin (aka TheRealSquirrelWhisperer) demonstrates. It's interested to see his cat's eyes move around the page as the effect appears elsewhere.

Watch MC Escher make art in this short documentary

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.”

The strawberries in this photo are blue

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:
