Watch YMovies. This work is a demonstration of one of Jacobs' Nervous Magic Lantern performances, which are created with a hand-manipulated projector and use neither film nor video. Highly stroboscopic and hallucinatory, these kinetic performances result in otherworldly spaces and plays of near-abstraction and suggestive imagery. Mountaineer Spinning features an evocative musical score. This work highlights Jacobs' relentless experimentation with the very fabric of projected light.
