There is so much going on over at the Art House Co-op these days. Their mission statement is "We build art projects and communities". I first learned about them when I checked out The Sketchbook Project.  You can find details on that here:  The Sketchbook Project
Now they have a wide variety of projects such as The Meal 2013, The Encyclopedia of Workspaces, The Print Exchange, Letters from Your Childhood, Things Found By Accident (a photography project) The Memoir Project, a handwritten collection of true stories from individuals from around the world.
There are several more as well.  I think that anyone could find something that would appeal to them.  If you are looking for a way to exercise your creative "muscle) Check out their projects site here Art House Co-op Projects
Check out the deadline dates for signing up as these projects are open for a limited time.
