An exploration into how the old VT220 terminals rendered font glyphs.
Follows advice from the classic two texts:

Originally I wanted to use WebGL but then in the name of getting something on the screen chose to render with DOM divs. Efficiency gods forgive me.
Dove into this after getting an old monochrome amber CRT myself and being fascinated with the aesthetic. It’s definitely a vibe :)
