Ponderings and fiddling with Raspberry Pi tiny computers.
With a bunch of stepper motors, some clever mechanicals and controller cleverness, it would be possible to build a motorized monitor stand controlled via a Raspberry Pi or similar.
Look inwards Mr Pi, see your self as you are and then you can be the change you wish to see.
AKA - stick a camera on a Pi, point the camera at the Pi, set it up to take regular pictures, compare them against previous pictures and log/alert someone if there is any change.
One of the first add-ons I bought when I started playing with Raspberry Pi Zeroes was the Pimoroni PiGlow. This is a tiny pHat (Pimoroni term for a tiny Zero add-on board) which contains 3 spiral lines of 6 different coloured LEDs.
