Props for a Film About Vision

Etchings on copper, 2017

Ophiocoma wendtii is a species of brittle stars that inhabits coral reefs from Bermuda to Brazil. It is known for its advanced compound eyes. Its arms are covered with calcite crystals, which in addition to functioning as an armor and giving structural support, the crystals make up its unique visual systems. They minimize spherical aberration and can detect the direction of incoming light. The lenses work by filtering and focusing light on an underlying photoreceptor system. Nerve bundles under each lens, presumed to be light-sensitive, transmit the optical information to the rest of the nervous system.The only known animals to employ a similar visual system were the now-extinct trilobites.

Circular Roof Window

Circular roof window is a depiction of a window designed by Eileen Gray’s Tempe a Pailla, 1934. Eileen Gray covered her horizontal windows with operable shutters. As she put it herself, “a window without shutters is like an eye without eyelids”. Through these innovations, Gray effectively layered the Modern strip window with apparatus allowing for personal appropriation through physical engagement, thus permitting a certain degree of controlled subjectivity.
