Escher Illusions in LaTeX
A drawing in TikZ.
The first picture draws an impossible brick, which induces
an optical illusion similar to that triggered by Escher's

The second picture draws a Penrose triangle, another similar
optical illusion.

Example Venn Diagram with isolated areas filled
This example helps to show how the isolated areas of a Venn diagram can be filled / coloured.
It was created as part of this answer on TeX StackExchange.
Other options for creating Venn diagrams with multiple areas shaded can be found in the Overleaf gallery via the Venn Diagrams tag.
