Inverted Geometry:
Light travels in straight Euclidean rays. Rays reflected from tree crowns pass through the tiny aperture and strike the lower floor, while rays from grass strike the ceiling, projecting the world upside down.
Dust Mote Illumination:
Tiny atmospheric motes illuminate the beam path inside the darkroom, forming a luminous conical hourglass.
