That's a very open-ended question. You may want to narrow it down a bit, unless you're truly just looking for anything.

Some helpful information would be your experience level (are you only looking to learn or is your goal to create something), what languages and frameworks you know, if you're looking to join an existing project or lead your own, what type of collaboration (collaboration could mean anything from working on the same git repo to remote pair programming), what you look to get out of it, how much time you're willing to invest, and other things in a similar vein.

You are looking for project ideas? I've made this huge-ass shell script for a asciidoctor package format (to make projects with media portabel). Then came the thought, i should redo this in python and then "while i'm on it, why not a universal lightweight markup package format?". But i don't have the time, so if you're up for it...

And the thing i don't have the time because, it's complicated. Maybe in a few months.

My project's currently on hold because I'm focusing my outside-of-work coding on stuff that helps me with my current job search. But once I'm done with that I'd be super interested in collaborating with my artist friends to get out of a UI/UX snag I've hit. Getting input from non-programmers on projects is always a really good way to move forward imo
