Tim Hawkinson tinkers with everyday materials to build surprising mechanical art works. “I guess it comes from early on in childhood, a fascination with moving parts and sort of the magical,” he suggests. In his studio, Hawkinson explains how he used gears, switches, nozzles, buckets, and pie tins to build a drumming machine that captures random drips of rain, amplifies them, and organizes them into music. “It’s not even electronics. I don’t know what it is,” he admits. One of Hawkinson’s largest projects, "Überorgan," is an inflatable installation in a space the size of a football field. For a version of the artwork the artists created a score for the organ using old church hymns.
