This Italian-made ten foot long corrugated pressboard sheet works as a divider, a fortress, and an adaptable playroom. With ten different panels featuring shapes, patterns, and colors, this 1967 piece is now in its second design run: faithfully re-produced by Edizioni Corraini. With the price tag over $100, we think customizing this idea even further with a DIY version would make for a great project (and you wouldn't worry so much about the destructiveness of hard play)...

You can find this at Chicago's MCA store online or in person for $110.
