Yes, Floyd-Steinberg is not the best choice for animations, 1-bit 
monochrome videos look like being played on a badly tuned ancient CRT 
b/w TV set... with YIP, I'll implement ordered dither in the future!

See you in Khyberspace!

I wasn't criticising just curious that Floyd-Steinberg is still enabled. 
Testing with Paintshop Pro I prefer stucki dithering or depending on the 
outcome, the nearest colour. Just a matter of personal taste, I suppose.

Well, you or at least I, cannot argue with that. To be kind it does 
remind me of some Op Art.

There must be some recidivists around. :)

Also there is typewriter art

I've always been one of those DIY guys, so back in the mid-to-late 1970's, I
built a (large!) one-note-at-a-time music synthesizer from kits made by PAIA
(John Simonton.) Tomita was my major influence to do so. The only trouble with
PAIA kits (at the time) was that they didn't use the standard 1-volt-per-octave
paradigm, that almost every other synth did. And it was purely analog; the
circuits would 'drift' slightly, requiring recalibration every now and then. But
along with my trusty 4-track TEAC reel-to-reel tape deck, that synth was an
astounding creative tool.

Sad to say, I dismantled that old synth years ago.

Now, the old synths (MOOG, ARP, and probably others) are all available in
software emulation. (And they would certainly be *easier* to use than in the old
days!) I haven't purchased one yet, but I might get the urge to
dive back into synth music in the future.
