A visitor places
money into a donation box, where sensors activate one
of four sound effects. The action of placing money
into the case also triggers a rowing model
immediately above the donation case. The model
consists of a 4m x 2.5m x .6m tank with water 35mm
deep running inside and four stainless steel oars
attached to a stainless steel block. When triggered
the oars complete a single rowing revolution through
the water, producing a ripple effect.
Running water is
pumped around the system from a header tank and the
correct flow is achieved using a flow regulator. A
semi-automated process helps with simple periodic
recharging and sanitation of the water system.
