Our Lady of the Heavenly Spheres

This is an adaptation of a Cathedral roughly the size of Notre Dame.

Marbles start at the top of the spire, and roll along a track in the roofline, in and out of windows, jumping into gargoyle mouths, along the flying buttresses, and into the upper heights of the cathedral, where there are a number of ball-activated features to symbolize the busyness of heaven as sculptured wooden angels are perpetually activated to flutter their wings, lifing people, play harps, etc.  At the altar there is a plinko game, whomever is praying at the location that the ball lands in gets their sins forgiven as well as a token to feed into the slot to start another ball down the track.

  When a token is fed into the altar slot below, a few balls are allowed to deviate to the lower tracks where they activate working saints, praying saints, worshiping saints, a nickelodeon playing some appropriate hymn music, a rotating kaleidoscopic stained-glass window(tm) and a waterfall baptismal.

Every hour, a ball rolls onto a diverted track which activates the hour chime, another carefully- coordinated rolling ball-activated masterpiece of mechanical music such as we've all seen online lately.

At the end of its journey the ball is lifted by Saint Sissiphus back up to the spire.
