Muller-Lyer Illusions
The Muller-Lyer illusion is an optical illusion in which two lines of equal length appear to be unequal depending on which direction the arrowheads at the ends of each line point. When the arrowheads point away from each other the line appears shorter. When the arrowheads point toward each other, the line appears longer. The illusion was first discovered in 1889 by German sociologist Franz Carl Müller-Lyer.
While the Muller-Lyer illusion is mildly interesting, the effect becomes mind blowing when movement is added to the arrowheads. Here are examples of Gianni A. Sarcone's dynamic Muller-Lyer illusions.

Siege of the U.S. Capitol: Timelines & Misc Videos
I started to write a timeline of the siege of the U.S. Capitol but found there's already numerous ones out there. No need to reinvent the wheel, especially since I have so little time at the moment. Here are some of the timelines I've read/viewed.
Written Timelines
Video Timelines

Trump supporters make their way up the exterior steps of the Capitol, pushing through barricades and knocking police officers to the ground.
Protesters (aka right wing radicals) breaking doors and windows and enter the U.S. Capital.

Schroeder Stairs
Schroeder stairs (Schröder's stairs) is an optical illusion which is a two-dimensional drawing which may be perceived either as a drawing of a staircase leading from left to right downwards or the same staircase only turned upside down. It is named after the German natural scientist Heinrich G. F. Schröder, who published it in 1858.
The Schroeder stairs appear in M. C. Escher's works "Relativity" and "Convex and Concave"

Super Illusion Brothers
The animation appears to show figures running up the stairs then jumping off. In actuality, they are stationary, except for the last figure which is pumping it's arms and legs. The image uses a 'reverse-phi illusion' to create the perception of movement.

Flashed Face Distortion Effect
From Wikipedia:
The flashed face distortion effect is a visual illusion involving the fast-paced presentation of eye-aligned faces. Faces appear grotesquely transformed while the viewer focuses on the cross midway between them. As with many scientific discoveries, the phenomenon was first observed by chance. The effect has been applied to Hollywood celebrities, and won 2nd Place in the 8th Annual Best Illusion of the Year Contest held in 2012 under the aegis of the Vision Sciences Society. The phenomenon, which has gone viral on YouTube, also represents an example of scientific phenomenology which outstrips (in this case) neurological theory. According to Susanna Martinez-Conde, president of the Neural Correlate Society, which hosts the competition. “These are the best illusions of the year, so they’re very new by definition. You’re going to know the phenomenology first, and the neural underpinnings second. Typically, we don’t know why these illusions work in the brain. We may have theories, but the experiments have not been done, because it’s too early."
