From the YouTube description:
Another automaton based on the mechanism used in the Climate Change Prognosticator. A color-changing LED lights the interior under the crystal ball, but its effect is not noticeable on video. The figure's arms are poseable to some extent. The head, hands and skull are sculpted in polymer clay. The skull glows in the dark. You may notice that the "future" can sometimes appear hazy — often falling between two symbols — a side-effect of the mechanism, which uses no gears or pulleys, and none of the moving parts are connected to each other.
