Works also on other graphical systems. Acme itself talks the plan9 graphical protocol which. There is an implementation of that protocol in the plan9 from userspace port (https://9fans.github.io/plan9port/man/man1/devdraw.html https://9fans.github.io/plan9port/man/man1/devdraw.html). I'm using it on macos where it's a native application with retina support and native macos fonts, native macos clipboard etc. IIIRC there is a web implementation too but last time I tried it it didn't work. YMMV
