Halftone Sun
A red sun and its ripples rendered as a live halftone screen: thousands of dots on a 15 degree grid, sized by brightness. Drag the sun.
What you're looking at
The picture is a simple brightness function: a disc, rings radiating from it, and a little drifting noise. It is never drawn directly. A rotated grid of dots samples it, and each dot's radius is set by the brightness at that point, so tone becomes size.
The idea behind it
Halftone screens let presses print photographs with a single ink. Each colour plate is rotated to a different angle so the dot grids do not beat against each other. The 15 degree tilt here is one of the standard screen angles in four colour printing.
Try this
Move the pointer to carry the sun across the sheet and drag the ripples with it.
