This charming steampunk hat by R.R. Martin contains a device which projects animated imagery. The device is called a zoetrope -- I would suggest watching the video you can see it in action. The device essentially spins sequential images, which turns them into an animated video.
The hat is currently for sale on Etsy. If purchased, the user would have the ability to create any animated motion they wanted as long as they provided their own images.
What is really special about the steampunk hat is how it is put together inside. Despite including a battery-operated motor, mirror, lens and the zoetrope, the hat is said to be light. The top hat also has managed to remain quite stylish.
