The U.S. Department of Energy's Princeton Plasma Physics Laboratory has developed software for an experiment that can be observed and controlled from anywhere in the world. And a lot of it has been developed by high school and undergraduate interns.
The Remote Glow Discharge Experiment (RGDX) consists of a hollow glass tube with air held under vacuum. Supplying a voltage of up to 2000V generates a glow discharge within. The user has control of the pressure inside the tube, the voltage supplied to the plasma and of the strength of an electromagnet surrounding the tube.
