Artist Chris Eckert uses the tattoo medium as a personal reaction against people being born into a religion rather than choosing one after research and reflection. This machine picks a religion at random and brands the willing subject with its symbol.
Auto Ink is a three axis numerically controlled sculpture. Once the main switch is triggered, the operator is assigned a religion and its corresponding symbol is tattooed onto the persons arm. The operator does not have control over the assigned symbol. It is assigned either randomly or through divine intervention, depending on your personal beliefs.
