The Piano Printer V3 - Marble Machine Physics Simulation (Wintergatan)

I've synchronized Wintergatan's Marble Machine (Piano Version) to about a thousand marbles bouncing on piano keys. The marbles are lifted back up to the top using gears so they can be reused. It was tricky to avoid jams in my dispensers, so I have some rotating parts to keep the marbles from getting stuck. For the finale, all the marbles are collected to form an image.
