To mark the opening of Art Unlimited, his happpening will be reinvented for the first time since 1967 in co-operation with the Department of Art and Design at Basel's University of Applied Sciences and the University Basel. Kaprow recruited participants using billboards that displayed the Fluids score: ''During three days, about 20 rectangular enclosures of ice blocks (measuring about 30 feet long, 10 wide and 8 high) are built throughout the city. Their walls are unbroken. They are left to melt''. At the artist's request, students will create a Basel-specific, contemporary variant of the happening.
