Face Cages is a dramatisation of the abstract violence of the biometric diagram. Diagrams are fabricated as three-dimensional metal objects, evoking a material resonance with handcuffs, prison bars, and torture devices used during slavery in the US and the Medieval period. The virtual biometric diagram, a supposedly perfect measuring and accounting of the face, once materialised as a physical object, transforms into a cage that does not easily fit the human head, that is extremely painful to wear. These cages exaggerate and perform the irreconcilability of the standardised, neoliberal biometric diagram with the materiality of the human face itself–and the violence that occurs when the two are forced to coincide.
