The whole of his life Kiesler developed his own world of art. The wide range of his artistic practice included distant disciplines such as architecture at first, painting and sculpture later, but also everything between these disciplines – he was working on applied art such as shop-windows, exhibitions, furniture design and topics dealing with the theatre. His theory of correalism, from the thirties onward, was a tie which connected his various artistic activities into a unique universally oriented system. Earlier, in the twenties, his design concepts were defined by a dynamic awareness of space, which was fed by the technical euphoria of modernism. Rather unconventional solutions developed from it both for the theatre and for the city and apartment developments.
