Last week, the 19th annual CANstruction competition kicked off, with teams of architects and engineers spending a night building sculptures out of canned food, which will be donated to City Harvest. Mixing art and design, the pieces must be visually compelling but also structurally sound. The cans are on view at the World Financial Center through November 21, and on Monday, the winners were announced at a big gala. Take a look at the top six entries as well as the rest—hopefully they’ll help get you hungry for dinner.
