This quick and easy project uses the Adafruit HalloWing to create a creepy Halloween mask from the seal found on the back of the one dollar bill.  

The Great Seal was first designed in 1782, and has been printed on the back of the one-dollar bill since 1935. 

The phrase Novus ordo seclorum (Latin for "New order of the ages") appears on the reverse side of the one-dollar bill, along with the phrase Annuit cœptis, literally translated as "[He/she/it] has favored our undertakings". 

An old pair of sunglasses (with lenses removed) or a headband can be used to hold this mask to the face.
