24 hours of Earth's rotation, with the camera locked to the sky instead of the ground. We're all hanging out on this spinning rock.

@coreyspowell Oh nice, do you need to have a battery connected, or is there a wire, I would imagine that the wire would become tangled after rotating enough, is there a limit to how many days this can go on for?

Most DC power cables are just two wires stuck together, one for positive and one for negative. There are many ways to connect a freely rotating electrical component to a non-rotating stationary power source, but one of the simplest is just a "tip-sleeve" or TS connector, similar to what you'd find on a standard electric guitar cable. And if the power supply has a third wire for ground (more common for AC power), you could use a "tip-ring-sleeve" or TRS connector, similar to what you'd find on a standard stereo headphone cable.
