"Colorful", a wonderful tessellation by Ashley W., a student
in Math Teacher Mary Jo Hughes' combination "8th Grade Math Class and Prism Sanctuary*"
in the lighter, more colorful part of Minnesota. Usually, I don't like geometric tessellations as much as I like tessellations that aim to resemble an animal, person, or object, but this one's colors are just so attractive and elicit a happy feeling, like a 1960s record album cover or something that swam by the Beatles' Yellow Submarine.
* No, not really. The other parts are true, though.
