Every winter a handful of Cajun Louisiana folk artists assembles unlikely mixtures of material to shape masks for their Cajun Mardi Gras celebrations. They use window screens, chicken feathers, yarn, hair, Magic Markers, and hot glue as they create fanciful, even bizarre masks that will be worn just one day in the year.

Such creations transform their wearers into wild revelers who move through the countryside singing, dancing, and begging for money and food. As they generate merriment, they climb trees, chase chickens, and create a general and playful havoc.
