Dude In The Jar Lamp. (Jail scene on left side)

These are only visible when the correct switch is on. Not a lava lamp but has a bubbler. Started out as an HP oscilloscope and a display inside a theatre where the scope was.. I like to add "Easter Eggs" into the lamps when possible. This one has a Schrödinger's cat scene and a guy in a cell working on the machine.
