While playing with puzzle cubes, I also used the cubes to create two classic illusions:
The classic one is name Necker Cube illusion. It was first published as a Rhomboid in 1832 by Swiss crystallographer Louis Albert Necker as stated in https://mathworld.wolfram.com/NeckerCube.html

Another example, which I like to call Illusion+ as it looks like a plus sign, is described at https://optical-illusions.fandom.com/wiki/Isometric_Illusion

Isometric illusions are also called ambiguous figure or inside/outside illusion.
