Acadalus CPS-H1 self-leveling camera head

One of the most difficult problems about shooting pictures with a camera on a tripod is keeping the camera level.

Generally, the bubble level attachment is for that, or you could get the Acadalus CPS-H1.
The CPS-H1 is a self-leveling camera head with a built-in digital inclinometer, and it can automatically level the camera at the touch of a button. I’m guessing that the other buttons are for subtly adjusting the camera for artistic angles.
