In the early 1920s, Surrealism emerged as a new cultural rhetoric and aesthetic rooted in using the element of surprise to open up new frontiers of the imagination, blending the playful with the philosophical.

Among them is this (very not safe for work, but then again so was the entire decade) erotic hand signaling chart, a naughty adaptation of the standard American Sign Language manual alphabet:

First person to adapt this into an animated GIF gets a piece of candy.
