notglossy: Man... I'm lucky if the fonts I'm using even have tabular figures as alternates. This is on a whole other level.
ilaksh: I guess it would be cheating, but he actually could have just written it in Rust, since OpenType can execute web assembly. People have abused that to embed things like Tetris and even an LLM inside of fonts.What he did was more impressive in a way.
userbinator: Not too surprising given that a font maps bytes into glyphs, and an instruction set maps them to instructions. I suspect a 6502 or 8051 version would be much simpler.
dhosek: Definitely. I wrote an incomplete z80 disassembler as a high school student back in the 80s, but never got to the 2-byte opcodes. 6502 has none of those so would be much easier to manage.
Averave: You can do a lot of crazy things with fonts. Just off the top of my head:Tetris Font - https://news.ycombinator.com/item?id=40737294A font which is also an LLM - https://news.ycombinator.com/item?id=40766791And in the same vein:Tetris in a PDF - https://news.ycombinator.com/item?id=42645218Doom in a PDF - https://news.ycombinator.com/item?id=42678754
pwnfunction: next is to build a disassembled inside a pdf
anthk: get zmachine.ps and you could play zork i-iii, Tristam Island and tons of z3 zmachine games (search for calypso.z3 too) without cheating as the PDF format implements an ad-hoc JS interpreter where not all viewers parse it.
iberator: Ha ha this is the best thing I have seen today in hacker news!So clever and funny
billforsternz: I thought my Z80 project (https://github.com/billforsternz/retro-sargon) was close to the whimsical end of the practical to just for fun spectrum but this takes things to a whole new level, kudos.
california-og: I made a syntax highlighting font (also mentioned as an inspiration to Z80 sans):https://blog.glyphdrawing.club/font-with-built-in-syntax-hig...
erk__: It's not OpenType that can execute wasm it's a experimental extension in HarfBuzz so compared to this it does not work online since it is not enabled for the HarfBuzz builds in Chrome or Firefox. Which makes this more cool to show of online.(disclaimer, I made the Tetris font)
aa-jv: My favourite is Chartwell - a font which can be used to add many sophisticated chart types to your document, using discretionary / rare ligatures:https://www.vectrotype.com/chartwellI've used this to rapidly add charting functionality to various apps over the years - it can be used to produce amazing-looking, dynamic charts, within minutes!I have, for years, wanted to dissect Chartwell and understand it better .. there are many other fonts which use rare ligatures for interesting purposes, too ..
