Sorry guys if I don't do a PR, I wanted to submit several identicons project.

Gradient identicons:
https://github.com/tobiaslins/avatar

Pixel art humans (I don't know if they're from Dice Bear):
https://avatars.dicebear.com/

Pablo Stanley's Bottts & Avataaars (identicons available at Dice Bear website)
https://bottts.com/
https://avataaars.com/
https://avatars.dicebear.com/

Gridy by Jan Forst:

Other version of Gmail avatars:

Face.js:
https://github.com/dumbmatter/facesjs

SquareIcon (looks a bit like Ethereum's Blockies):
https://github.com/mistic100/squareicon

Libravatar offers a "retro adventure character" identicon but I don't know where they found it:
https://www.libravatar.org/tools/check/

Identiconizer! uses 2 types of identicons that I can't seem to find either: Dot matrix and Spirograph
https://forum.xda-developers.com/showthread.php?t=2718943

RoboHash offers 3 other types of beside the default robots set: monsters, other robots and kittens
https://robohash.org/

It would be super nice if we could provide a custom seed to neural networks that generate a photo like https://thispersondoesnotexist.com/ or https://thiscatdoesnotexist.com/
Would be also nice if there existed such neural network but for landscapes.

Maybe there are examples of moving identicons (GIF for example). I don't know if there exists audio hash "visualizations" but I know some examples for text:

Tripphrases by Bret Victor:

Proquint Prononceable Identifiers:
https://github.com/dsw/proquint

Besides I think you should put a table of contents in the header of the README. You should also sort a little bit the different types of identicons IMO, for example:

|- Characters
   |- Robots
   |- Humans
|- Geometry
   |- ...

Maybe you could submit Awesome Identicons to the "Master" Awesome repo:
https://github.com/sindresorhus/awesome

If I find the time in the week I will do a proper PR.
