This website is pretty cool. It’s a shader algorithm with the goal of rendering an image pixel by pixel, but it relies entirely on human calculation, with no computers and no calculators. Claim a pixel, and follow the instructions to calculate the Red Green and Blue values of the pixel you have claimed.
All of the pixels have currently been claimed, but they do expire after a while, so just wait around a bit and you might be able to contribute!
Yes but this is the kind of thing PCs are uniquely better at so it kinda feels like a waste of time. I prefer my collaborative efforts to go towards something which enrich the commons. That’s just my take however you do you.
