My first entry in to Jan Svankmajer's world was with "Neco z Alenky", a surreal take on Alice in Wonderland that drew me in instantly. After watching "Neco z Alenky", I immediately started looking for more material by Jan Svankmajer, and I came across this little short animation which blew my mind out of the water.
During the 6 minutes of "Tma/Svetlo/Tma" (Darkness/Light/Darkness) we are invited to witness the different parts of the human male body entering a room separately and trying to figure out how to complete the human form. During this, the small room gets more and more crowded and difficult to move in. To me, the message this short gave me was that we should not aim higher than our capabilities, or we might end up with our goals crowding a small room, eventually turning off the light on it. But this is my interpretation, I've read several more interesting ones as well.
If you enjoy surreal / abstract cinema art, you owe it to yourself to watch this short as soon as possible, you will not be disappointed.
