I wanted a way to cycle through a list of live webcams, that are freely available, as well as local sources from CCTV security cameras; so I created the MMM-iframes module . The example configuration includes YouTube live embed urls and the salesforce tower cameras as well as other random live webcam feeds. If a keyboard is connected, buttons can be configured to switch the camera feed source arbitrarily and cycle through the list of cameras faster than the configured update interval. I don’t use my MagicMirror behind a mirror, and have only tested this with a desk monitor.

@draxiom Nice! Don’t forget to add it to the modules list: https://github.com/MagicMirrorOrg/MagicMirror/wiki/3rd-party-modules :-)
