Swing Etching Harmonograph.  2012.  The machine makes an etching by scratching a thin layer of black paint off of a white translucent acrylic sheet. One swing controls the up and down motion, whilst the other controls the left and right. Together two people make a drawing based on their swinging. The machine etches two identical plates side by side, and each participant gets to keep one. Etching plate size 187 x 250 x 2mm.
