“A screening of ecstatic moments created with the Video Feedback technique at the event horizon of perceptible worlds of image and sound while generating a moving picture. Moments distilled from experimental videos and compiled into a new unit.
Video Feedback is mapping (imaging) any visual event (image) to itself through parallelism and circulation. A minimum change of its instrument positions (video camera | screen) generate a maximum of stimuli at the time-based event horizon of perception. A flood of rapidly changing abstract images on the move will be experienced as a world of spatial complexity and of dynamic states.”

“Pointing a live video camera at its own projection gives what is known as a “video feedback loop”. The camera reads the screen and then projects the image, in a repeating vortex. By carefully adjusting the angles and standard controls on a mid-1990′s-era video camera, Ethan Turpin isolates the self-sustaining patterns. The real-time animation can move from patterns resembling pantheistic design to microorganisms expanded to a human scale, evoking the uncanny feeling that life has emerged from within the system. Participants can move in the space between the camera and projection screen surface, integrating into the abstracted image.”
“Kaleidoscope feedback,” Peter from Xinaesthetic, 2009
Caption: “I’ve been playing around a bit with doing video feedback through a kaleidoscope shader.
In these images, the ‘seed’ that is fed into the feedback is simply the plain black or white background of the window. There is a single rectangle rendered with the output of the previous frame as a texture, which is fed through a GLSL shader which inverts colour and applies a kaleidoscope effect, resulting in rich chaotic imagery.”
