u/recursive

Direct pixel manipulation. Interesting approach but it looks like it might always be larger. Does this have a dweeting application?
u/hypothete

I'm not sure. I put this one together in case people had ideas on how to shrink it.
u/veubeke

@hypothete new ImageData(W,H) saves some bytes as does incrementing i by 1 instead of 4 and calculating image data size manually. https://www.dwitter.net/d/2069

Created in iOS/Safari. In Windows/Chrome, when not in fullscreen, it looks like there's a stronger Moire effect.
u/MonteChristo

How !!!

Well, I can say it's far, far more trial-and-error than by design :)
