The Illusion You Need To See
You have probably seen this rotating window illusion before, but Derek dives into it (heh heh). He looks at anamorphosis, which is creating distorted images that only look 'right' when they are viewed from a particular vantage points.
Towards the end he comments on how when people are presented with information, different people can come to wildly different conclusions, which kind of explains the eternal state of human society.
In recent years I have noticed a spate of chalk artists drawing illusions on sidewalks, often of holes in the ground. But the technique has been in use for a long time, as this painting from the 16th century shows.

The blob in lower foreground is a distorted human skull. Derek uses this painting in his video. I can just barely make it recognizable by looking at the screen from a very low angle, so low, the items on the screen almost disappear.
