Calling all artists!
Many of the images available in the user avatar gallery are... a bit dated.
And also, there really aren't very many of them.
We should redesign or replace most of the really cartooney ones that have square backgrounds, and add more that are a bit better-looking. In particular, we should add more nature, animal, abstract, technology, vehicular, and sports imagery. Normal people love this stuff--two of the most popular user avatars on macOS are an owl and a basketball. They should look good.
