Stereoscopic 3D view of Earth rotation 

The video, captured from Google Earth, which unfortunately did not complete a full rotation, is a stereoscopic 3D video. Relax your vision so that the screen doubles, and adjust your vision until the two frames overlap in a third, middle frame. If done correctly, the middle frame will appear in 3D. It is easier on a smaller screen. It’s best on a cell phone held vertically. The center of each image should be about an inch apart. Not good on large computer screens or iPads.
This is another experiment inspired by Steve Reich's Clapping Music. It involves a repeating rhythmic/melodic pattern that follows the circle of fifths with each repetition. The pattern shifts one eighth note with every harmonic change.
