Some of us may have grandfathers that we remember seeing blow smoke rings out of their pipes -- the Hee Park 'Architectural Time Machine' is an imitation of that, being a large machine that blows perfect smoke rings.
In his last year in architecture school, Park has put together a complex configurations of fog machines to create this masterpiece. Wafting out of what look like mini cannons, this architectural feat is impressive as the smoke rings hover for a sustained amount of time before dispersing into space.
Though this was just a school project and these machines may have no foreseeable practical use for them, the possibility of shape-making smoke machines may prove attractive for the entertainment industry. Can you imagine how cool it would be to see a ghostly lion float across the stage in a Lion King musical?
