Creating a “Magical Checkers” Illusion

In this week’s free episode of Deke’s Techniques, Deke deke-constructs another optical illusion in Adobe Illustrator, inspired by a variation on the cafe wall illusion by artist and magician Victoria Skye.

Deke begins with some straight purple lines, deftly and mathematically drawn by using Illustrator’s Move command and Copy option.

Which suddenly become bendy and slanted thanks to a series of checkerboard shapes added at the corners:

And they needn’t be checkered squares, either. If you’re a member of or LinkedIn Learning, you can check out Deke’s exclusive movie this week in which he turns those squares into a group of dots, and yet the illusion remains the same.

Even circles give the illusion of bending
