Also very, very nice idea for 4k demo. Yeah, remember me to childhood.
I wonder how ALL the data for drawing points/lines could be stored only in just 4k? Seems to be a lot.

So many treats lately around the Revision party  :) . Wonderful demo. I mean, is it real that this demo can even run on 4K resolution? No wonder why achieving it got some monitors broken !  :o  Weldone to the team involved

It may answer your questions.

But in fact, Crinkler https://github.com/runestubbe/Crinkler, the cruncher, does every thing here ;) The data are stored in a dumbed way that crunches well; which is not the case of more clever ways. Just though of another way that would use twice more bytes unrunched but would probably crunches even better. I may try it

The data are encoded thanks to some macros defined here: https://github.com/rgiot/demo.revision2024.etchy/blob/master/src/commands.asm
Here is an example of use https://github.com/rgiot/demo.revision2024.etchy/blob/master/pictures/stonks1.asm
A program convert some bunch of PNG images to that https://github.com/rgiot/demo.revision2024.etchy/blob/master/convert/src/main.rs
