The Leaf Faerie Headdress, featured on Adafruit's blog, is inspired by the Russian Rusalka Myth. Rusalka came out of the water in the spring to transfer life-giving moisture to the fields and thus helped nurture the crop. However, Rusalka had a dark side, and if you came to close to the river, they might drown you. The headdress transforms from a whimsical and magical garland to an eerie glowing headdress in the dark. Much like the light and dark of the Rusalka.
