I looked everywhere for these icons. Turns out, they were on my machine all along, burried deep inside. I extracted each icon and threw them on a sheet in Illustrator for easy access.

If you own a Mac then you already have these icons on your machine here:

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. Years ago, during the development of the first Macintosh, Bill Atkinson (of HyperCard, QuickDraw, MacPaint & now nature photography fame) discovered a very elegant dithering filter to convert greyscale image data for the 1 bit black & white Mac video display. The dithering produced by this routine was much higher quality than the now-a-days ubiquitous Floyd-Steinberg or “Error-diffusion” filter (used by QuickTime, PhotoShop).
