there's a moon during a lunar eclipse in the top right hand corner, but i don't know the physics behind it. when i was in downtown LA late at night, many buildings were lit up. i imagined all the volts that were required to light up one building. i pictured diagrams of wires with current flowing through them. i also imagined the electric box that contained all the switches that controlled the lights for one building. i went from a simple circuit to a gigantic circuit in a office building. coool.
