Last few days for Anthony McCall exhibition

Drawings are at Spruth Magers (from whose website this photo is borrowed; on the website is a link to an interview with the artist) and the "light works" themselves are at Ambika P3, Baker Street.

"Four digital projectors beam elongated wigwams of light from the ceiling into the haze-filled space below. Each projector creates a shifting pattern on the floor, forming the “footprint”, as McCall calls it, for the ever-evolving structures that hover in mid-air.

"The effect is calm, meditative, otherworldly — as if McCall is expertly manipulating moonbeams, or somehow tethering the Northern Lights within a gallery.

"All four works, presented in the UK for the first time, were made since 2004, shortly after McCall — who was recently commissioned by the Arts Council to create Column, a twisting spiral of cloud that will rise above the River Mersey as part of the 2012 Cultural Olympiad — began producing art again after a hiatus of two decades." says this article.
