The background

TLDR - it's primes with a bit of color

It started off as a thought - how would prime distribution look like visualised on an image?
After coding a script that would spit out an image, here's how it looked like:

white points where both coordinates are prime

From here on, I already thought this would look like a nice background for something, but for now it was too vibrant and monotonic.
Experimenting a bit with only the brightness I eventually arrived at this:

color determined by (x * y) % 256

Already better, now to introduce some color. I ended up with lots of variants, most of which you can explore here.
By far the best one turned out to be the background you're seeing right now.

colors: red across the horizontal axis, green across the vertical, small amounts of blue randomly thrown in
