Essay by Alexander R. Galloway on Nils Aall Barricelli in Cabinet -“Proceeding in lines from top to bottom, Barricelli’s algorithm produced a rectangular image consisting of a grid of genes appearing as individual pixels. When finished, the image yielded a snapshot of evolutionary time, with the oldest generations of organisms at the top and the youngest at the bottom. The output of Barricelli’s experiments was highly visual. he was essentially drawing directly in binary numbers, converting 1s and 0s into pixels in either on or off positions. Because he represented each gene as pixels, organisms were identified visually based on how the pixel patterns self-organized into texture fields, which were identified as shapes or zones within the image. Variations in texture delineated one organism from another, and the width and height of any given texture field indicated the lifespan of an organism”](http://25.media.tumblr.com/tumblr_lracfcgibA1qcvwrgo1_1280.png "http://banquethall.tumblr.com/post/10019730790/image-digital-image-resulting-from-a-2010")
