Blue Grid Background with a Sphere
Interesting experiment by Tom Doyle that is full of grids with a sphere (resembles the sun) in the center. The grids have been formed by using CSS3 Repeating Linear Gradients while the Sphere is the result of Radial Gradients. If you have worked with CSS3 Gradients before then it should be fairly simple to figure out how to customize it. Try changing the color of body in the code editor (or web developer tools) and see how nicely the live preview of the item changes.
