"Sculpture for Travelling"

Where would modern art be without Marcel Duchamp? Here's just one of his newfangled old Readymade inventions -

Bits of rubber (cut from bathing caps) that can be assembled (randomly - and extended with strings) into a sculpture, wherever you are. It was made to be recreated out of his suitcase at every stop during a voyage in 1918. For three or four years he had a number of these in his studio, so that the strings impeded movement around the studio ... very playful ...

Another of his "voyage sculptures" is a typewriter cover - an invitation to voyeurism (could you resist peeping under it?)
