@soatok I drew dicks when I was 8. This would get me in big trouble so I created a dick pic obfuscation scheme. I'd make lots of random folds on a piece of paper then draw my smut on the transformed paper. When the paper is unfolded (flat), the pictures looked like nothing (they were 'encrypted'). Only through proper re-folding would the forbidden image be revealed, analogous to the application of a security key. Unfortunately the folds left physical traces in the paper which could be used as a side-channel attack vector so I was forced to abandon my work as a pioneer in crypto-art.
Now it's 40y later. I still draw dicks and I work in cryptography. :)
