Intro: The artwork of David Spriggs lies in a space between the 2 and 3 dimensions. In his work he explores phenomena, space-time and movement, colour, visual systems and surveillance, the strategies and symbols of power, and the thresholds of form and perception. Spriggs is known internationally for his unique large-scale 3D ephemeral-like installations that use a technique he pioneered in 1999 layering transparent images.
