Echo of Motion is a collaborative performance between an autonomous cybernetic installation and a human performer. The work is an interpretation of my relationship to my own Tourette's Syndrome. The performer has accelerometers sewn into both sleeves and both pant legs. The control panel on the performer's chest sends these movement signals via wireless radio to the autonomous system (the machine) The machine is autonomous and may acuate movement with or without the human performer present. The machine's body is a modular construction of wood dowels, laser-cut plywood, 3D printed parts, ball-chain, gear-motors, cables, and various nuts and bolts. The brain resides in the central control box that houses the electronics and jacks for connecting the multiple motors that run through the installation. The human performer stands within the the work and performs his tourettic gestures. The machine responds with movement, and retains a memory of these gestures. When the human is gone, the machine continues with lonesome sporadic echoes of motion. This work was installed at our MFA thesis show -- the Mirage and the Rainbow at OSU Urban Art Space, Feb.-Mar. 2014.
