Transmedia artist Guy Overfelt created this massive inflatable "smoke" installation for the Cantocore Export Guangzhou show in China a couple months ago. It follows the thread of Overfelt's previous Inflatable Trans-AM. From the description of the piece, titled "Untitled" (Up in Smoke):

This time the inflatable Smoke is fabricated in Guangzhou, factory direct. Beyond Paul McCarthy-like reductive shapes coming off the assembly line or the Chinese Olympic team leaving the others’ in the dust, the simple shape raises questions about what these factories are pumping out in Guangzhou.
