Great way to expand one's graphics knowledge: Every day grab and read a random graphics paper from realtimerendering.com/random.html. Even if you struggle to get the specifics, read the abstract or skim over it to learn about its existence and get the gist of a graphics technique.

Happy new year! May you impedance match to your audience and radiate like a dipole antenna. (or a phased array idk what far field pattern you desire)

GIANT NERD ALERT: I finally have a clone of one of my teenage BASIC experiments in one-dimensional cellular automata, based on an article in Byte I’ve been lugging around as a photocopy for 33 years. I even recreated the Apple IIe color palette. Thanks to fourmilab.ch/cellab/manual/….

I really enjoy the logistic map. I was a bit surprised over the interesting 3D distribution of the detail clustering that happens in the chaotic regions after R=3.5.
