mechanized multimedia

Various artists in the 1920's built contrivances to give an immersive, multimedia experience

• Laszlo Maholy-Nagy -- The Light-Space Modulator
• Kurt Schwitters -- rooms (Merzbau)

Some think that the operatic composer Richard Wagner was the first artist in cyberspace.

• 1876 -- state of the art opera house in Bayreuth

to integrate all existing art forms: music, dance, poetry, painting and architecture.
