You’ve got a week to build this portrait, whose eyes follow you around the room, for Halloween.
Adafruit have produced a tutorial, courtesy of Tony DiCola, which uses OpenCV and openFrameworks with your Raspberry Pi and camera board to create a picture of pullulating panic. It’s haunted hardware of horripilating hideousness.
You’ll also find instructions on making your own frame in the tutorial: we recommend making one large enough to drill a hole in, so you can conceal the camera board inside before using this to scare your loved ones. It’s elegant and spooky; plus, you can keep it for the rest of the year and use it for another OpenCV project like the Magic Mirror.
