How the Pattern Board screensaver works
No data connection is used at all — the saver generates its own geometric patterns entirely in your browser.
It cycles through stripes, checkerboards, rings, waves and static, each riffling into place across the board.
A new pattern arrives every few seconds, so the board keeps clattering through fresh art.
Board size (rows and columns) is adjustable, and a click sound can be switched on in settings.
A worked example
Diagonal stripes clatter across the board, hold for a few seconds, then riffle into a ring pattern, then static — generative flap-art with no two cycles quite alike.
Settings & tips
- Board width/height resize the grid — try a wide, short board for banners.
- Flap click sound adds the mechanical clatter (off by default).
- No internet connection is needed; every pattern is generated locally.
