You see the lit up skyscrapers and the outline of the mountain backdrop behind the buildings. You also see the waterfront along with parts of the water. Invisible: The flow of people. This includes within the buildings (elevators, walking), in and out of buildings as well as the traffic and underground subway which is moving people back and forth. Since it's night time, it is most likely people have moved away from the financial district back into their residential neighborhoods. There is also the use of electricity which is sort of visible due to the light emitted but air conditioning, equipment among other things are also being used. Finally, there is also flow of data that is invisible here. All these buildings are connected to the internet and so financial trades or even just basic browsing would contribute to the flow of data in and out through the various internet nodes.
