I'm no artist but while I was working on adding user avatars to the comments section, I felt it was too plain to just show nothing for users without an avatar. So I spent a few hours sketching my own lemming and turned it into a feature! Starting from the next update you will be able to have the app generate your own lemming avatar and set it as your profile picture.
The app will also display these lemming avatars for users without a profile picture to make the comment section more lively when user avatars are enabled.
That's very cute. Excellent idea, I've not set a picture for myself on my main account so that others don't feel bad for not having a picture. I might set one up in the new year though.
It reminds me of the old Gravatar concept, or how some blog systems used to generate a random image based on a hashed email address (maybe that was the fallback of the Gravatar scheme)
One of the goals later down the line is to draw a dozen of these avatars and make the avatar selection also randomized. An even more ambitious idea is to make the avatar itself generated. The avatar is currently a vector. That means each point can be manipulated to be in a different position and have a different curve. So the paths can be given bounds and randomized based on the user's details. This is a bit of work so I'll probably only do it for fun when more of the app is fleshed out.
