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.
Here's my Pi Zero that runs Apache, Grav CMS, and various other webby type stuff. It serves this blog site internally and acts as a general playground for me to mess about with a web server.
Big pile of waffle about things I should do with the Pi Zeroes I have kicking around the place now.
After the PiGlow, the next Pimoroni add-on I tried for the Pi Zero was the Scroll pHAT. A little board with a block of 5 x 11 white LEDs.
