In Parametric Expression, a pair of nude, hairless computer models repeat the same off-putting facial expressions in a digital limbo that seems to exist somewhere between the uncanny valley and hell. Sometimes the faces will glitch out, blooming into a blood-colored biomass of intertwining polygons. Other times, these visages will just twitch and leer, pulling back their muscles into ever-intensifying rictuses that, in humans, would cause their facial muscles to roll up like window shades. It’s disturbing name implies, Parametric Expression is ultimately about what happens when the expressions on the faces around us–the wistful smile, the sarcastic smirk, the suggestive grin, the angry grimace–are converted from muscle memory into parameters an algorithm can understand.
