Y combinator codex (2021)

The Y Combinator Codex is a calligraphy piece created in Kraków, Poland, between January 13th-25th, 2021. The artwork measures 420mm x 2400mm and includes white margins on both short sides. Various tools were used in its creation, such as Pilot Parallel calligraphy pens, Hero and Pelikan inks, Ecoline watercolor paints, Ecoline metallic gold paint, and Vallejo metallic silver paint. Inspired by the Y Combinator Codex by emacsomancer, the piece is in very good condition with minor wrinkles and a small tear. Printed copies will be available for purchase, and the original piece will be auctioned during the European Lisp Symposium 2021, with proceeds going to Lisp-related organizations. Details on how to participate in the auction will be announced at the conference.

Curiously, in the pure lambda calculus with Church numerals, the factorial function doesn't need recursion, since Church numerals already act like iterators: fac = λn.λf.n(λf.λn.n(f(λf.λx.n f(f x))))(λx.f)(λx.x) or as a lambda diagram:

It's beautiful, but isn't a codex a book? I thought that's what separates them from scrolls.

Nice to see that yin-yang of eval/apply floating in a sea of King James 1611

this is amazing work, looks hand done. can't imagine the time that goes into something like this, just figuring out how to compose it... and not making mistakes?!

very cool

Should sell mostly prints but some originals on Etsy.

A regrettable name. Everyone who sees it will assume that it's something like 'a startup self-help book'.
