Natalie Jeremijenko is an artist-experimenter. Her projects and those with an artists' collective called the Bureau of Inverse Technology have consisted of creating devices and situations for the purpose of gathering overlooked facts. These data sets and the means by which they were formed range from the Despondency Index (for which the Bureau installed a motion detector camera on the Bay Bridge in San Francisco, recorded suicides, and graphed the relation of suicides to stock market and other data) to Tree Logic (1999) at MASS MoCA (in which six live trees are inverted and suspended from a truss, displaying the contrived growth responses of the trees over time). In this age of the commodification of information, Jeremijenko has made data her medium.
