Anamorphisms effectively encrypt or hide images. The
reasons why images may be so hidden are many, including
political content, sexual content, religious propaganda,
a mix of these, or just simply a form of playfulness.
The anamorphic image above encrypts due to erotic
content. The decrypted image is of an unclothed couple,
the woman passing a money poch from her man to someone
behind the curtains.
