The Dolly Zoom

"The dolly zoom is commonly used by filmmakers to represent the sensation of vertigo, a "falling away from oneself feeling", feeling of unreality, or to suggest that a character is undergoing a realization that causes him to reassess everything he had previously believed."

This is the filming technique I was describing for the Gorilla-activation shot. I think storytelling wise its a great fit because it creates that jarring 'unreality' we want associated with the mind-world right away. Most people use the effect simply because it 'looks cool' but we actually have a need and purpose. If you've never actually tried it with a real camera, its basically done by dollying out your camera (a tripod with wheels) while zooming in or vice versa. Here are some examples:

Visually whats happening is the 'subject' remains the same scale and position in the frame while the background changes perspective and scale. This shift is unnatural to the human eye thus creating that unsettling feeling. I've never seen it done in animation - but everything is possible! (except sleeping 9hrs a day)

I'll play with this for the final leica reel - it should totally be in it. Hopefully this clears things up.
