Some art movements have bigger impact in the world of graphic design than others. Optical, or “Op” Art made an especially grand entrance in the mid 1960s.

While the movement receded from the art world relatively quickly, making room for the Warhol-led Pop Art, its red carpet continues to roll triumphantly through the worlds of logo and packaging design. Here, Op absolutely still “pops.”

Feast your eyes: this is actually part of a magnificent wine label design by Meeta Panesar

In a nutshell, Op Art refers to geometric patterns that are mathematically designed to play with visual perception or produce an optical illusion — a sensation that the actually-flat surface is three-dimensional or moving.

Some of these designs really seem to swell, roll or swirl. Others take the form of shapes that are logically “impossible” or have two incompatible interpretations.

Trippy stuff.

In this poster advertisement for Spanish bank Caixa Catalunya, stationary spirals appear to move. Focus on one and it will stop. Are you freaking out yet?

How about now?

Most of the Op-inspired graphic design work is a little more subtle but the influence is clear. Check out these radical logos, book covers, posters and packages:

The logo for the 1968 Olympics in Mexico City was distinctly Op Art-inspired
