How are they planning to get rid of errors?
the final step in the worksheet provides an error correction heuristic and procedure: > Thanks a lot for being part of the Human Shader, go find your pixel in the public canvas! Tip: if its color looks wrong to you, feel free to review your calculations and submit again with the same code!

It's really interesting seeing the (what I assume are) error pixels.
The author should implement an error correction system, where 1) the result is withheld from the display until a second corroborating calculation comes in, and 2) if there is disagreement, request an arbitration from a third user whose job is to pick which of the two is the best answer.

the moderators are checking that the pixel was computed by hand, not that it's correct
The page does actually say they want to see intermediate results “so we can validate your work.” (Edit that quote has been removed now.) But there’s no promise that they will. The photo feature may be more of an automated speed bump, a way to reduce silly answers and pixel spam, and let people self-select, than an active human moderation tool. Moderating is boring and expensive in time and/or money, why would anyone…
This was fun, I forget sometimes how silly all our grade school math worksheets used to be. I always had trouble showing my work for simple additions and multiplication, it's a bit easier when its a self motivated dunking on the GPUs. It may take 4-5 days and 1000+ people, but it's definitely created a greater sense of community than any faster rendering system. I like looking over the different pixels and knowing th…
I think something like this would actually make for a really interesting 3rd grade class project, with each student contributing a few pixels.
When completed, it would show a QR code, that upon scanning would mark completion of the workbook and show you the answer key. The implicit idea being you didn't have to be perfect, just good enough so the error-correction algorithm of QR codes was enough to pick up the final image. (Probably extra credit if you could figure out how to do as few problems as needed and then use EC to still figure out the secret link)
so someone can just write a script to generate the full image right? since instructions are the same for each pixel. Would make it easier to check your work.. edit: https://imgur.com/a/UO37L1b

It is a bit odd; they specifically ask for the picture of the worksheet, and say they’ll check it. I wonder if the just haven’t gotten around to it yet. Automatic error checking would be nice (IMO just let multiple people do each pixel and take the most popular result).
They ask for the worksheet to check that you're not cheating. They don't check the pixel values. I think much of the charm of the image is seeing the errors. By the way, there's more going on in the shader algorithm than you might expect. Here's an explanation of the worksheet: u, v are coordinates relative to the center of the image h is radius from center, squared Section B generates the ball: B3-8 generates the re…

Ah, I remember seeing some chinese summer math workbook shared online where the answers to each problem could be translated into a bit that could be plotted in a giant grid on the last page. When completed, it would show a QR code, that upon scanning would mark completion of the workbook and show you the answer key. The implicit idea being you didn't have to be perfect, just good enough so the error-correction algori…
For the lazy: pick a pixel in the sky to skip to section D (less calculations)…
