This video looks like a rotating wheel. But watch just one single sphere. It never rotates. Every ball only moves in a perfectly straight line back and forth. This is simple harmonic motion where linear position follows: x = R cos(ωt) By perfectly offsetting the timing of each straight path, the collective motion creates the illusion of rotation.

This Lissajous Machine is straight-up sorcery. Two cranks at 33:37 ratio, linked arms, and x=3cos(33t), y=3sin(37t) weave a perfect lattice from thin air—no pixels, just raw harmonic motion. Trig functions don’t just describe beauty. They are the beauty.
