If you Love Somebody set Them Free

[tracker7]

In one move or another, a shitload of my track has gotten misplaced - some switches and all of the curved track. So, there went about $60 to replace it. Now I've got the track to put this thing together.

More tech issues. The trackball's crapping out. Replacement is ordered - a first-generation Magic Mouse, because every wireless trackball I could find uses a USB receiver and the Magic Mouse 2 requires macOS X 10.11 or newer.
