⇒ They don't call them canned goods for nothing. Through December 8, you can stop by the World Financial Center in New York City to view the results of the 16th annual design/build competition known as Canstruction, in which teams representing 40 of New York's top architectural and engineering firms compete to create giant structures made entirely from canned goods (the giant sundae at right, for example). Co-presented by the Society for Design Administration and the American Institute of Architects, the exhibit will ultimately be dismantled and all of the canned food will be donated to City Harvest for distribution to emergency feeding programs. There's no charge to get in, but you're encouraged to bring some canned goods to help the cause. (Finally, our hoarding of Del Monte wax beans pays off.)

⇒ Depending on your time management skills, you can go right from admiring that adorable non-perishable Humpty Dumpty to T-Minus, an annual screening of media art that focuses on the manipulation of time. Organized by Chris Jordan, this year's festival takes place tonight at Galapagos Art Space in Brooklyn and promises a gathering of "exceptional realizations that explore the union of digital media and time." The exploration begins at 7 p.m., but we have a feeling that everyone will be late.
