    Now this was the shiznit. High quality stuff, a great explanation and very cool animations. Some of my computing profs would love this link.

    Fun dithering fact: the original Macintosh has its own distinct dithering algorithm, which was developed by the late Bill Atkinson. (It's probably the error diffusion method that this demo calls out.) It's part of the visual charm of the classic Mac.

      I bet the author will cover Atkinson dithering. Though I didn't see anything in the demo that indicates they had that specific algorithm in mind: error diffusion is a whole category (e.g., Floyd-Steinberg, Sierra…) of which Atkinson is one variant.

    This is a good explanation for how dithering works with some slick animations

    I can't say I'd ever before really thought about how dithering would be done, but now after seeing it threshold maps feel so intuitively obvious. I'm rather confident though that it's one of those...

    I can't say I'd ever before really thought about how dithering would be done, but now after seeing it threshold maps feel so intuitively obvious. I'm rather confident though that it's one of those things that only feels obvious in hindsight because I could feel myself being drawn to overcomplicating it when the question was posed a few slides earlier.
