You’re looking at a piece of Mac history. In the early 1980s, Bill Atkinson developed a technique for displaying tonal images on the original Mac’s 1-bit screen. It became legendary—then disappeared. In 2003, Bill shared the algorithm with Tinrocket founder John Balestrieri, who documented it for the community and built HyperDither.

Hello, Color

Palettes so smart, they optimize themselves. HyperDither analyzes your image and builds the perfect palette automatically—or switch to a uniform palette for a raw, digital look.

Big Names, Small Dots

Atkinson. Floyd-Steinberg. Stucki. (And friends.) Each algorithm has its own character—some scatter, some stipple, some cluster. Try them all and pick your favorite.
