Painter of sharp-edged abstractions, digital images and large fiberboard environments and parcel-like sculptures, Olaf Holzapfel (born 1969) makes works that might be formal evocations of Gilles Deleuze's folds and "deterritorializations"; their appeal lies as much in their abstraction of cerebral processes as in their material facture. "The Nomadic Criterion" is a survey of his work from the past decade.
