The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears as a tiled mirror. As you approach it though, the tiles shake around and make it very difficult to follow what’s in front of you. It’s an art piece and a prank all in one, and we like it.

Behind the mirror is a 3D printed frame and a set of small servos with what look like some belts to hitch them up. There’s an ultrasonic sensor and an Arduino Uno, that sets those servos going as soon as the ultrasonic sensor sees anything. We can see this thing would be fun at a party.

Everything you’ll need is on the Instructables page linked above should you be foolhardy enough to want your own, and there’s even a YouTube video which we’ve placed below.
