This is the demonstration of one operator "folding" it states. Break -->break/break(rotation)-->break(vortex) and so on.
The field is projecting the pure function of the operator. This results in a simulation like "material" shown on the screen.
What ur seeing is just a fraction of the "material" due to computing power. If u increase parameters of visualisation - which are scaleable extremely. It results in plasma fluid like material - but be careful this is a very intense simulation.
Also it is kinda cool because u can make a truelight-plasma-laser-disc :)
