Every Pixel Soup wallpaper starts as one of these. None of them is a picture file: each is a small program that your Mac runs, which is why they can move, and why no two come out the same.
Flow. Bands that bend around each other like marbled paper. The one to start with.Mesh. Soft blobs of colour that swell and merge. The calmest of the lot.Plasma. Overlapping waves, the classic demo-scene effect from 1990s home computers.Ripple. Rings spreading from two points and crossing, like two stones dropped in a pond.Aurora. Vertical curtains of light along a wavering band. Dark above and below.Cells. An organic mosaic whose walls shift, somewhere between stained glass and a leaf under a microscope.Topo. Contour lines over rolling ground, like a walking map.Whorl. A spiral that turns slowly. Op art for your desktop.Sonar. Islands with depth rings around them, as a chart would draw them.Mosh. Bands of signal that slip and tear into static. A broken broadcast, on purpose.Weave. Ribbons going over and under each other in a basket weave.
One shape is thousands of wallpapers
These are single frames in one palette each. Change the seed and the same shape rearranges itself. Change the palette and it is a different mood. Change the dither and it goes from a smooth gradient to newsprint dots or ASCII characters. Scale and Warp stretch and bend it. Then it starts moving.
