Escher style Geometry Art from J. R. Masterman's 9th grade geometry class

abstract geometric (alhambra-style) motif first-time tessellation by a child

SHOW YOUR SUNNY SIDE by Phoebe

Phoebe tells us this is not an abstract geometric tessellation. It's breakfast.

"The white part with the yellow circle in the middle is supposed to be a fried egg, sunny side up! I carefully did the brown shading in the egg but it did not show up very well on the computer. Then the orange red thing is a sun!"

Phoebe's careful shading would look just perfect in print, where adding colors together makes them darker. On a computer, we add colors together to make them lighter-- and that makes the delicate nuances between light yellow and very light yellow difficult for a computer monitor to show.

Also, Phoebe's art has run up against the way that computers keep color information in tightly bundled files called "JPEG". JPEG files are like suitcases for images: a big image can be compressed into a small size. That's great for images that we send across the Internet: smaller is better, on the Internet. However, just like suits get rumpled when they're crumpled in a suitcase, images also suffer in very compressed JPEG files. They get little wrinkles called "JPEG artifacts", and their reds become faded and less-obvioiusly shaded. (Other colors are more resistant to wrinkling and fading.)
