Stationary Electron Microscope
From Live Cinema Research
- from wikipedia, which also has information on other types of Electron Microscope.
Basically a large metal tube with lots of mechanical looking things sticking out of it, a large power source (maybe glowing/sparking), and a screen attached.
This is a view from a Scanning Tunnelling electron microscope of two small bumps (impurities) in a metal surface
Possible prop - photo developing machine on the roof
