List of the prompts for Genuary 2023 is announced: https://genuary.art/. Genuary is a generative art daily challenge wherein we create an art piece for given topic (prompt) and share it somewhere in the net. So if Advent of Code is not enough for you, join the Genuary :)
Any recommendations on what libraries to try for this challenge? Processing was my first real programming experience so I am thinking about looking into Quil, which seems to have a similar spirit. Clojure2D also looks interesting. Maybe even a more restrictive, minimalistic approach could be worthwhile.
Quil is ok. I use Clojure2d (cause I wrote it :) ). My last Genuary code is here: https://github.com/genmeblog/genuary
There are articles describing how to use p5js or d3 from CLJS (Quil does it too). Si if you prefer frontend dev it can be a good choice.
