I should be working on my mask, but I wanted to look at some last minute inspiration 1st. One of my favorite Doctor Who episodes is "The Girl in the Fireplace", which is about the life of Madame du Pompadour (the mistress of King Louis XV of France) as seen through "time windows" from a space ship into her realm. In that episode there are clockwork robots that wear Venetian Masks and intricate wigs over their clockwork heads. Inspired by my favorite episode, I did a Google search for "venetian masks". These are some of my favorites.
