My Avatar Generators: Cats, Birds, Fenestars and Abstracts

Published on

Hey, back in 2016 I decided to get rid of trackers on my website, and Gravatar was one of them for the comment section. That's how I decided to make my own homemade cat avatar system based on sprite I painted. Then I made birds, received sponsoring by Framasoft for the Fenestar one of Mobilizon and also made an abstract one. You'll find them all here:

We love the cat generator here at home ! I have already adopted 583f13c94f5f5 :-).

Cool! I found one I really like through random generating (583f7b02633e4), but now I can't find a name that will give me that one!

Cute writer one! What name would you like? :)

link 583f7b02633e4   - Reply

Hmm... I'm not sure... what names are there that already give that catvatar?

link David Revoy Author, - Reply

I can link 583f7b02633e4 to the nickname you want :-)

link 583f7b02633e4   - Reply

I'm not good at coming up with nicknames. :/
How about "Misty Tales"?

(Incidentally, the capcha I just got said 'k1ty', almost like 'kitty'!)

Ok for Misty Tales. It should work now :)

(ps: oh oh, nice for the capcha! :3 )

Maybe I need to choose a name without a space in it?

Ha, my fault! Sorry, now it's working, with and without space. :)

Oh, there are multiple easter eggs in generator, by the looks of it. Nice work by the way!

I might have peeked at the source to satisfy my curiousity.

Haha :D Now I know the words you tried to type in the generator xD

Hi David. Thanks for the Cat avatar generator! I really like mine. The markings on its blue fur look like Oriental brush strokes. And I like the typewriter and monocle -- they reinforce the cat's image as a curious, investigative writer and editor!

By the way, this is my Chinese name. My English name produced a different cat avatar. It's exactly like your Carrot avatar, David, except that mine has a blue scarf wrapped around its neck so its mouth is covered haha.

I really appreciate your fight to prevent Google from exploiting your readers' data and privacy and the sacrifice it entailed. Thanks a lot for that. Hope you have fun during the holidays!

Thank you Yi Jing!

I'm hoping at some point that there are easter eggs for Truffel and maybe even the correct cat-colors for Yuzu and Mango.

Also hoping for "Pepper" to have a big floppy hat and a mini-broom.

Wanted to suggest that when checking for string equality for easter eggs that you make the check case-insensitive.

Might also be worth parsing some of the bad word lists freely available on Github for the obscenity detection. Not sure if its worth extending to sub-strings (which causes you to run into the Scunthorpe problem) or common substitutions.

Hey pop; if you are motivated by continuing the project, feel free to clone/git it, and add the features, more easter eggs, etc... I'll be happy to keep hosting it. Here I need to focus now on episode 20 of Pepper&Carrot. If I start to tweak more this code, I'll spend month in it. ;-)

Wow! This is great; much better than those boring default images, and it is free!

Thanks a lot!

It's nice that you care about privacy. And I'm happy something so awesome came out of it :>

I like "cat", But i'm sad "Tux" and "Kiki" aren't easter eggs ;P

Quelle bonne idée, ces catavars :-)

Just wonder if anyone has created a WP plugin for it?

link Eibriel   - Reply

David, congratulations for your switch to more privacy friendly options.

I did a Telegram Bot to generate avatars taking advantage of your "API":

I've added the link to this page, so it should drive some traffic here.

link Eibriel   - Reply

Your Avatar Generator is a success (at a modest scale) in Telegram, the Bot had around 1800 requests so far and 4 (over 5) stars on the store bot :D

Thank you for the news! Good to hear users likes it.

Note: I also made a new version, a bit more 'cold' and not funny, for my other blog on :

I just created a WP avatars plugin to display those cute cats.

It passes the test on my machine, but I know it's buggy. I appreciate if anyone could run it and leave feedback about any issues.

Je voulais répondre à Abner...
Attention David, si tu utilises ma version, tu risque de ne pas avoir les mêmes avatars que ceux générés par ton script.
Avec mon plugin, la différence avec le tien, c'est que les images sont en base64. Le chargement est donc théoriquement un peu plus rapide.

Ha oui, le Js de Pluxml deconne pour faire des 'reply' ; Jamais réussi à savoir pourquoi; ça le fait sur et

Merci Jerry Wham pour la version PluXml ( et toutes les contrib Pluxml ; je lis activement le forum ) et merci pour les améliorations!
J'ai aussi un autre thème d'avatar ; plus classique :

This is so cool. I LOVE orange cats, so I wish it generated more of them. lol

link Anon   - Reply

In using the generator, I've noticed that it generates more brown, tan and gray cats, than any other color. Is there a way to make it generate more of the other colors? That would be awesome. :)

Merci pour le message sympa Yann!

I am building a project based on this concept. The development tool uses your cat gen for proof of concept (only i have access at the moment).

In order to increase randomness, i apply a greyscale filter to cat, eyes, mouth, fur, and accessorie, then colorize it based on the first 6 characters of a sha512 hash.

Using savealpha you can maintain/set a transparent background. This enables custom/random back drops... Add some random picture frame pieces and wallah...

link David REVOY Author, - Reply

Oh, that's pretty cool method about using the gfx asset for their gray value est recoloring them on the fly. I'm curious to see visual about it!

Also i disabled accessories and they unlock as you level up. You can choose your look so to speak

link David REVOY Author, - Reply

Thanks! Funny result. It probably would require a bit more work for the color to affect only the Chroma and keep the gray value in order to solve problems of contrast and part becoming too dark and too bright (inheriting the value of the random color).

The mechanic of getting accessories as bonus is nicely thought!

link Joshua Dungan   - Reply

Yea it gets some odd results when I let it run unlimited color range. The final build will use limited color ranges on certain things.

But the concept is interesting. Maybe better applied to generating random quilts or something but the club I am making has magic and things, so a red eyed green kitty is fine lol.

I am launching a club for Brave using the cat artwork you created. On the footer of every page I have a credit/link back to your site. There is only cat art within the club right now but eventually will be icons on the homepage.

Our goal is to create a network of people who want a safer, faster internet using Brave and to extend beyond that into a better, safer, healthier planet. I liked your posts about anti-CDN and have generally tried to adopt the theory when building the club aside from api libraries which I will eventually host on my own server to be 100% CDN free as well.

Thanks for your work David!

The club has a mouse hunt game featuring these awesome brave little kitties. Check it out if you get a chance.

That's more than perfect Joshua; thank you for the update, the video example and all the work around your community. I'm happy to see it used for that purpose.

Thanks for the relay! I have it on my bookmark, scheduled for reposting tomorrow (today and yesterday I was busy on both Twitter and Mastodon; so better to not flood too much posts at once). François was in contact with me during the steps of this animation and made a fantastic work. That's really high quality.
