Post your ominous signs

@liamvhogan For anyone that's wondering, the phantom that room contained was this thing, the UK Schmidt Telescope's phantom. It is a specialised electro-mechanical computer, used by the telescope's original control system to keep the telescope dome and its windscreen aligned with the telescope itself. It has since been exorcised from the phantom room and banished to an unused office.

The pointer in the middle of the phantom was linked to the telescope drives, and pointed in the direction the telescope was looking. As it moved it pushed the white arch (representing the dome) and the D-shaped frame (representing the dome windscreen) around. Sensors on the arch & frame were linked to the dome & windscreen drives, making them follow the telescope. The phantom enabled the UK Schmidt Telescope to do real time coordinate tranformations without needing an electronic computer at all from 1973 to 2013.

Photos by me, from 2019.

@drew @liamvhogan it was totally bogus, dude

It gets crowded, especially on a Saturday night!

@joannaholman @liamvhogan This feels like someone tried to argue that the consistency of melted ice cream made it neither Food (solid) nor Drink (liquid) and they were just done with that person’s shit.

@drew @liamvhogan I'm so cooked I thought this sign was saying that if the lights stop working then the last person to post a bill would get charged
