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.

In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same.
The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.

Huh, TIL. The "transform normals with inverse transpose matrix" is not ideal, turns out. Adjugate matrix is both better and faster to calculate. See github.com/graphitemast... and shadertoy by iq himself: www.shadertoy.com/view/3s33zj

It's been pretty great. Immutable, declarative, and very very simple. Just some files, a list of packages, and a short script.
