There are tons of arts and crafts projects that can be done with recycled bottles, jugs, and boxes. Some more extensive projects include walls or green houses made from recycled 2-liter bottles. 
When I was asked to make an owl mascot/costume out of recycled materials for the Mighty Kindness Hootenanny, I didn't think it would turn into such an extensive project.
This is the making of Hootin' Annie.
