Hey, we—Eevee, magical, habnabit, Inaki, and some others—are building an art site.
It's not really ready for primetime yet, but you can try it out if you'd like.
Want to know where we're headed? We have a lot of ideas.
If you want to keep up, there's a sporadically-updated news feed, or you can hit us up on IRC.
The backend is called "floof", a name the site itself used to share.
It's written in Python, atop Pyramid). The code lives on GitHub, though the bug tracker is separate.
We've got a separate technical IRC channel if you're interested.
