Katie Paterson's conceptual, interdisciplinary practice combines a scientific, research-based approach with a clean minimalist presentation. Focusing on cosmology, ecology, and geology, Paterson's intimate works engage the viewer with monumental ideas of time and the cosmos, as in Vatnajökull (the sound of) (2007–08), a neon phone number that connected callers to sounds culled from a microphone submerged in the meltwater of an Icelandic glacier. For Light bulb to Simulate Moonlight (2008), Paterson approached OSRAM, a manufacturer of daylight bulbs, to develop a bulb that emitted the quality of light of a full moon.
