Here’s a few font experiments, more or less sensible, that you should be aware of:
- Heikki Lotvonen’s text highlighting that is built into the font itself. Does not use HTML, CSS or Javascript.
- llama.ttf that has an “AI” (LLM) built into the font itself, so when you write !!!!!!!!!!!!!!!!!, every ! is replaced with a word. (check out the links at the bottom of that page too)
- Fontemon – world’s first videogame in a font.
