A showdown began last night in Minneapolis... it's Barebones Productions versus Galumph Interactive Theater in a competition called "Dumpster Duels." It's descrbed as a "puppet free-for-all". Inspired by cable-TV's "Junkyard Wars," each company will transform a dumpster full of bike tires, chicken wire, cardboard, used furniture and other materials into puppets, props and a set for a brand new show that will be performed tomorrow night. Last night, judges tossed a coin to determine which pile of junk each team will be making their art from.
