Remember canned food drives in elementary school? Harken back to the days when one can meant saving the world and get inspired by giant works of art made entirely from cans. Canstruction, a national non-profit, fosters awareness for the fight against hunger by holding citywide can art competitions. Each year, local architects, engineers and designers build giant-sized structures out of donated canned goods and put them on display around the city. Check out the unique exhibits at various locations including the Weston Art Gallery, the Downtown Public Library and the Scripps Center. Participate in the challenge by bringing non-perishable canned or packaged food to display sites. Cincinnati Canstruction proceeds benefit Freestore Food Bank. For more information, visit www.cincinnaticanstruction.org. On display through March 19.
