Theater director E.F.Burian developed together with Miroslav Kouřil the so-called Theatergraph a performance stage with integrated projection surfaces on which films and slides were projected during theater performances, and established a direct visual relationship to the onstage action. This technology was first used in 1936 for Wedekind’s production of Spring’s Awakening, and later for Pushkin’s Eugen Onegin, wrote Denis Bablet in his book, Scenography of the Twenieth Century: "Alongside the theatrical research work of Piscator Traugott Müller, the experiments of Burian and Kouril helped pave the way to new theatrical forms in which the projection screen and colors no longer characterized stage design. These came to be replaced by architectural structures, light, and projected images. A new civilization of audiovisual communication was born."
