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)

Caption:

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.”
