The Museum of Northwest Art in La Conner, WA, has an annual auction of work from invited artists. Lin McJunkin, an artist who works in glass, was asked to put together a glass collaboration of artists who work in anything but glass. Several of us gathered at Lin's to do our pieces and others met at the auction preview to create their pieces "live". We actually each did two squares so Lin had a bit to choose from in composing the final piece. It was such a hit at the auction, that she was asked to combine the 2nd squares into another piece for sale. Lin created the back piece to the platter, about 12", I think.
Mine is the center square.
