So I am making a program which uses a "futureistic" graphical interface. My problem is that though i have seen examples of it in the past, i cannot think of what to call it when searching through google for refrences.

An example would be a semi-transparent circle with semi-transparent "C"'s rotating around it but intersecting with it. The circle would be the top layer with the rest below it. The image would always be in motion.

I would like to know what it is called. Sorry if I confused anyone, im slightly confused as to how to explain this. Ask me questions so that I can explain anything.
