I don’t know what to call this pattern, but I like it!

Image 1: “The Maze” by Debralee Wiseberg (link and another gallery)… I think it’s corroded metal?

Image 2: 2,2-(Bipyridine)(Naphthalene)-fusion melt (25x)

Ethan Turpin, Video Feedback: Pixel Behaviors, 2010,

Sight-specific installation, Kala Studio, Berkeley, CA 2010

“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.”
