Does or has anybody seen a wallpaper that is full of random math equations? Quadratic equation, binomial theorem, integrals, limits and logs, matrices, etc.

If not, can somebody make one with a blue background with a white font face where the font look like handwriting? I've been trying to make one, but not really knowing what I'm doing. I was going for a blueprint look, or maybe just a black background with white font face.

TIA!
