When it comes to decoration for Halloween, or setting up an elaborate, Scooby Doo-esque plot to scare a bunch of meddling kids, it's hard to beat a creepy skull that looks at you out of one eye whenever it detects movement!
You can build this with the HalloWing and its TFT display, a lens, and a PIR sensor to determine when people are approaching, and then open up it's one good eye!

Clear Acrylic Lens Holder + Hardware Kit for HalloWing
The perfect kit for mounting a convex lens (glass or plastic) to your HalloWing! This holder has been laser-cut specifically for lenses with a lip-edge
The PIR sensor works best with 5V power, so battery usage will be better for a non-PIR reactive build. If you must use battery power and PIR you may want to add a PowerBoost converter for 5V power.
