Ask HN: Is there an online community for finding creative projects to work on?

I have been looking around online recently to see if there are any active communities online where people can post their projects for others to see and maybe contribute to in some way and on the flip side for others to find things they'd like to be a part of. There are of-course places like GitHub and whatnot, but I was wondering if there were places that aren't just about software. I ask this as I'm currently trying to find people that'd be interested in working on a project I've started. But also I'd really like to see what others are getting up to.
