Title: DEMO: Teaching an Old Dog New Tricks
Post by: Pixel_Outlaw on July 01, 2026
I've always had an interest in the Lisp and Smalltalk projects at Xerox PARC in the 70s through the 90s.
Recently, there have been great efforts (https://interlisp.org/) to revive Medley Interlisp, a pure Lisp OS designed for Cold War Era AI and beyond.
This is a very old dialect of Lisp but it's still interesting to use. (I'm generally a Common Lisp guy).

Anyway, they've got a BITBLT function and that means demoscene stuff IS possible.
I may do more if there is interest, but twisting a DARPA funded AI OS that only runs Lisp is fertile ground for cool hacks.

This is a WIP, I may do more if there is interest.

You can download a personal copy of Medley for Linux, Mac, and Windows currently.
Paolo Amoroso has good build instructions (https://journal.paoloamoroso.com/how-to-build-medley-interlisp).
The repository is here (https://github.com/Interlisp/medley).

See the attached image, hopefully it animates...
