What if you could compute the output of complex algorithms just by viewing an image?
Our everyday visual perceptions rely upon unfathomably complex computations carried out by tens of billions of neurons across over half our cortex. In spite of this, it does not “feel” like work to see. Our cognitive powers are, in stark contrast, “slow and painful,” and we have great trouble with embarrassingly simple logic tasks.
Might it be possible to harness our visual computational powers for other tasks, perhaps for tasks cognition finds difficult? I have recently begun such a research program with the goal of devising ways of converting digital logic circuits into visual stimuli – “visual circuits” – which, when presented to the eye, “tricks” the visual system into carrying out the digital logic computation and generating a perception that amounts to the “output” of the computation. That is, the technique amounts to turning our visual system into a programmable computer.

Gödel, Escher, Bach, Tumblr Gödel, Escher, Bach, Tumblr is an online book group. We're reading one chapter a week of Douglas Hofstadter’s 1979 masterpiece book about artificial intelligence, mathematics, consciousness, puzzles, music, and language.
They've been reading since the start of the month, so start in the archive

Fascination with ground and figure
carries on in various fields after The Rubin vase / face Illusion
, M.C. Escher
, and Marshall McLuhan
Besides being extremely important in the fields of photography
, the figure/ground relationship is important to physicist Paul Davies
, who says "the true miracle of nature is to be found in the ingenious and unswerving lawfulness of the cosmos, a lawfulness that permits complex order to emerge from chaos, life to emerge from inanimate matter, and consciousness to emerge from life."
Also, Peter Grundy and Yiang Yan discuss how contextual ground relates to linguistic figure
in Bill Clinton's famous apology,
plays with the distinction between sound as environment and sound as music, and W.C. Richardson creates paintings
in which "positive and negative spaces seem unstable; figure becomes ground, ground becomes figure."

An animated film based on a woodcut by M.C. Escher. Slow to load, beautiful to watch (and listen to).
