Ouija service bell for roboticists

[Kateaclysm]

Other codebases have this in the form of a "Positronic personality detector" type device that lights up when there's someone that's interested in latejoining as a borg/etc. I could definitely work here, but latejoining as a borg requires backing out from being a ghost and using the latejoin menu rather than it being a seamless transition from ghost > borg, so it may need to have some differences, or a ghost role queue system, etc.
