Quake E2M1 on CRT - Gameplay

Found this by accident: cssQuake - Quake running in the browser, rendered entirely as HTML/CSS 3D geometry via PolyCSS.
No WebGL, no canvas - the geometry is actual DOM nodes you can inspect in devtools while playing.
What used to choke on weaker hardware decades ago now runs as pure CSS layout/paint.
Open source on GitHub too.
Have fun!
