Hello!
I made a painting to spy on my guests.

I've printed a picture of Barad-Dur on the canvas.

Cut a hole on the Sauron's eye place for a spotlight with a focused beam.
I connect the spotlight to the painting throw 2 servos and servo brackets.
To make the beam more visible I added a fog from a fog machine.

Next, I realized 2 versions for tracking: on Arduino and Raspberry Pi.

For Arduino, I used Sharp Range Meter with a range from 0.2 to 1.5 meters.
I write the code in XOD. It'll be in a zip file below.

For Raspberry Pi I used a Raspberry Pi camera and algorithms on Open CV.
Description for Open CV is very large and will not fit into the article here.
But I strongly advise you to read it if you are interested.
