This program is designed to create simple optical illusions of the kind known as tri-bars and four-bars, made famous by Oscar Reutersvard, Roger Penrose, and M.C.Escher. You can make impossible connections of cubes by using pre-drawn pieces.

Anamorph Me !
An anamorphosis is a distorted image that can be restored by looking at it in, for example, a cylindrical mirror. A few centuries ago this could only be made with a lot of craftsmanship, but luckily you can try this program.
