spiral-chute-accrete

A full-bleed ambient background reproducing a gravity spiral chute, the helical slide used to move bulk parcels/mail sacks between floors in sorting facilities and department-store stockrooms without powered conveyance. Parcels drop in at the top, descend the helix in continuous view, and pile up in a landing area at the base until the pile is periodically swept clear.
