Yesterday I saw the movie "At Land" from Maya Deren. It's in black and white and doesn't need any sound. The movie was done in 1950 but it still looks very experimentel. Experimentel in a "Positive" way ! It still seems to inspire todays filmakers, I was reminded of a Moby video (don't know the name) and even a tv show from my childhood "the man from atlantis".

Here is a introduction on here, Ifound on the web:
With the advent of 16mm equipment came the birth of film as personal artistic expression, and Maya Deren led the revolution. The woman who was "her own avant-garde movement," had what can only be described as an eclectic set of interests. She immersed herself in political science, journalism, English literature, classical ballet, Taiwanese kickboxing, and Haitian religious rituals.

Calling herself a "visual poet," Deren catalogued disparate images and explored their shared relationship to an emotion or symbolic meaning, the latter often left to the audience to ascertain. Her movies are haunting, lyrical, and breathtaking fusions of human and cinematic movement, where the actors dance with the camera. Though called a heretic by those who worked with her, she was the first person to receive a Guggenheim grant for filmmaking and the first woman to receive the Grand Prix Internationale in avant-garde film at the Cannes Film Festival.

I liked this introduction to Maya Deren the most, but I will link (soon) to more detailed articles at the bottom of this article.
