"Zeitgeist’s Annual Shrinky Dinks Art Invitational. Almost every year, during a First Thursday gallery-walk showcase, Yeck invites artists to make pieces out of the retro toy medium called Shrinky Dinks. The sheets of blank plastic can be drawn upon, colored, painted, Xeroxed, printed on, and cut into forms. Placed in a hot oven, they will shrink to a third of their size in seconds. At his Invitationals, begun in 1999, each tiny work is auctioned off, with proceeds going to charity."
