What better way to celebrate the day after Thanksgiving, which is both Buy Nothing Day and the biggest shopping day in the Western World, than by enjoying some rebellious tactical media? We've got just the caper: a subvertisement contest sponsored by the Banner Art Collective. Peruse the entries, or enter your own subversive banner in the contest by November 28. The winning entry, which will be announced the 29th, will win a prize of $0.00 (zero US dollars), as one would expect from a parodic, semiotic contest such as this one. There weren't many subvertisements posted as of press date, but one, 'Apocolyspe Soon,' was amusing. -- Rachel Greene
