You can also do entertaining things like determine if a factory/data-center is running at full capacity by looking at the fans in the cooling stacks. Satellites take the red, green, and blue channels separately at different times so you can see if a fan is spinning through the apparent chromatic aberration of the blades, same deal with anything else that spins or moves. If you know the satellite you're buying imagery from, its TLE and a little information about the sensor you can work out all sorts of fun details.
