A shallow circular tray, covered with glass and filled with a pearlescent fluid, is heated from within its base. Instead of becoming more disorderly, as most things do when you heat them, the fluid organizes itself into an intricate pattern of lozenges not unlike the whorls of a fingerprint. Visitors may interrupt the pattern by spinning the disc, and observe the process as it reforms.
