Westwater's land art practice involves found images and objects, walking, documenting and storytelling. Weiche Maschine (soft machine) is an Arduino-driven animatronic, video stills of the animatronic traveling the world, a 1:35 scale military diorama and a PowerPoint presentation about a mysterious object discovered in North Africa during World War II. Interiors and Ruins employs antique and vintage postcards to evoke spaces of introspection, witness or disaster. Photographs taken in Berlin, Dublin, Reykjavík and elsewhere identify found marks, objects or nature as land art.
