I asked around, and was told it's like a show of miniature dioramas.
Often times in a large diorama, you would see mini-dramas happening, such as say a diorama of 16th century London with dozens and dozens of minis around, and there would be a sword fight in there with two minis, and such.
A lot of the minis had day and night displays, with the lights dimming and lights within typically from a building turning on. Lots of resin water dioramas, which are neat to see. As a modeler myself, I recognize how much work went into a lot of these dioramas.
In many cases, you press a button to get trains moving, or knights jousting, or propellers spinning, and such.
Topics range from the middle ages, to fairy tales to WW2 to logging sites, to bits of Canadiana and BC history
You enter and there would be a space station diorama and what looks like a belter (asteroid mining) operation.
