Studio 3, the Species Hinge, was a semester long project that foucsed on a question: why would a caddisfly and a watchmaker live together? My project is one of multiple scales and has two sides. The site box has the ability to move over a period of one year and, as it moves, creates perfect and imperfect conditions for each resident. Side A is the caddisfly side, which is composed of 5 separate wooden "lines" which contract and expand over time. WHen the lines are completely streched out, the water which normally floods side A is flushed into side B and side A is in the imperfect condition. When the lines are competely pushed in, side A is in the perfect condition because the caddisflies have the maximum number of places to live. Side B is the watchmaker side, which is a series of thin planes which conceal and reveal five separate residence areas for the watchmakers to live and work. Over time, these planes slide over the residences, which protects them from the elements and from the water which slowly fills side B when side A is in the imperfect condition. When the residences are completely covered, side B is in the perfect condtition. The compression and expansion of the two sides are controlled by five central control units. While the two sides operate in two different physical scales, they respond to each other until the end of the lives of both residents.
