Diuresis is a period 90 oscillator consisting of two bookends hassled by complicated eaters. The original oscillator was found by David Eppstein, and was hassled by pentadecathlons. With a minimum population of 66 cells, this is still the smallest known form of the oscillator in terms of cell count. Later that same day, Dean Hickerson replaced the pentadecathlons with the still life arrangement. The form to the right shows two still life arrangements, one with the minimal population (left) and one with the minimal bounding box (right).
The name is due to Bill Gosper, who compared the bookends to kidneys.
