Andrej Bauer started a Random Art Project that generates expression trees that describe an image. An interesting part of his random art is the functions he uses. He does not use a generation algorithm to create his artwork.
His website for his artwork allows viewers to rate the artwork and sort the pieces by popularity.
I admire that Bauer creates an abundance of different pieces. His artwork has a specific”style” that really represents “Andrej Bauer Art”. Because the pieces are so different and diverse, yet still similar through the style, viewers can tell a certain piece is created by Bauer. One critique I have is that his website is fairly limited and doesn’t reach a wide audience of people.
