At my first internship, I handled the GUI for an application used to simulate networks on a large scale (I remember 20,000 machines being the "small" test-case we used). There was a view where you could watch all of the devices in the network, and could zoom in/out to see the entire network at once, or individual devices. I remember playing a lot of SupCom to help me get an idea of how to zoom smoothly and how to handle the overlays/information density at every scale (also because it was a badass game).
