Brenez and Martin argue that "Brakhage’s films propose a tutoring of the eye, a rapturous attentiveness to the tiniest visual fluctuations and effects."
Somewhere in the article, they quote Brakhage himself:
"This eye is a jelly, and it’s quivering continually, with our heartbeat, with our walking, with our breathing, with anything that happens, any movement we make. And what I did was to make an articulate dance with that possibility, with this lens."The image is from Cat's Cradle.
