From Extreme Craft:

One of the great exhibitions that we saw over the weekend in San Francisco was Cardburg at Cell Space. Cardburg, which was devised by the shadowy “Cardboard Institute of Technology”, is an expansive installation that exposes the inner working of an entire city-state made of….you guessed it, CARDBOARD! Interpretive signage tells you about the lives, the loves, the myths of this complex city. Nature intrudes on the urban landscape–cardboard clouds, trees….and haunted caves vie for attention from the viewer. The threat of incursion by “Ducksquatch” is omnipresent.
