Protein Homology Network, data visualization by Alex Adai, Institute for Cellular and Molecular Biology – University of Texas, 2002

“The network summarizes the results of aprox. 92 billion pairwise amino acid sequence alignments between 289,069 proteins from 90 genomes. The final network is composed of 27,325 connected sets summing to 7,940,873 edges. An edge is colored blue if it connectes 2 proteins from the same species, and red if it connects 2 proteins from 2 different species. If that information is not available the edges are colored based on layout hierarchy.”

“These basket stars were observed offshore Norway at the Midnattsol field. They are at the top of a ridge on the seabed at 928m depth using their branched arms for filter feeding in the strong currents. ”

That second one has its mouth facing up — there are photos out there, but watch out — it’s nightmare fuel! (see also: Sarlacc)

Via this excellent photoessay!

Madreporites on sea stars

The madreporite is a lightcolored calcerous opening used to filter water into the water vascular system of echinoderms. It acts like a pressure-equalizing valve. […] Close up, it is visibly structured, resembling a “madrepore” (stone coral, Scleractinia) colony.” — Wikipedia

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

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.”
