Oh sorry one last thing, 400x400 will be rather large for the reference, where examples are typically use 100x100 for pages like https://p5js.org/reference/p5/createFilterShader/. Could we maybe do the same here? There's also nothing wrong with a framebuffer larger than the main canvas, but it may be helpful for illustration purposes to also make myBuffer fit in that size too.

No worries

We maybe don't need the push/translate/pop since the translation is 0 here, but otherwise this is looking good!

Can we make the size of the box to be 50 i.e. box(50) instead of 100

* // Get the color of a pixel at the center of the box (in 2D coordinates)
* myBuffer.loadPixels(); // Load the pixel data for myBuffer
