Israeli artist Liat Segal has created a device that uses light to print fading messages onto photosensitive paper. The Confession Machine uses ultraviolet (UV) LEDs that are programmed to switch on and off at certain intervals in order to print people’s confessions onto paper coated with a UV sensitive pigment. Then they disappear.
The work, commissioned by Artists’ Residence Herzelya, uses photochromatic paint developed by the Bloomfield Science Museum in Jerusalem. In total, 16 UV LEDs are used to flash in sequence, creating dots and dashes that, together, spell out the confessions pulled from social networks on the paper’s surface.
