HyperDither is sure to bring back memories of the early days.

The description from the developer:

HyperDither is an OS X image processing utility that converts color or grayscale images to 1 bit black & white using a sophisticated dithering routine. Specifically, HyperDither implements the Atkinson dithering filter.

Way back in the early days of Macintosh, Bill Atkinson (of HyperCard, QuickDraw, MacPaint & nature photography fame) developed a very elegant dithering filter to convert greyscale image data to the 1 bit black & white Mac video display.I was able to email Bill Atkinson in January, 2003 and inquire about the details of the algorithm; he was kind enough to respond with a brief write up of the routine—15 minutes later I had it up and running.

It’s taken a few spare afternoons since 2003 to pack everything into a nice little application with documentation and an icon—better late than never!
