A project that functions as a proposition (play of the imagination)

Every Icon

A grid 32 x 32 with every combination of pixels on or off take a very long time: 16 months for every combination on the top line (4.3billion). To make every grid black would take several hundred trillion years.

Digital Image Visual Syntax

Reference: The structure of Language
  • Discreet units: char (which are organized in a alphabetic symbolic system)
  • Chars are organized into pre-defined groupings (words: which convey ideas)
  • Words are organized into sentences based on rules off syntax
  • Syntax defined by common usage, and changes over time
  • Creative use is in how to create unexpected and innovative relationships with the rule-bound structures to achieve the play of imagination
  • Function of the "play of imagination" is to arrive at unexpected relationships to allow for new insights

Basic Unit: the Pixel
  • Pixel organized in relationships with other pixels: x,y location coordinates
  • Clusters of pixels make up the image. Pixel value complexity determined at this level (color depth1, 2,4,8,16,24, etc.)
  • Pixels have color values (0-255, or r,g,b)

Meaning Thru Nearest Neighbors Relationships
  • Meaning is created through pixel values in relation to surrounding pixels.
  • The relationships are rule-based
  • Information Theory describes some of the rules (randomness, sequence, redundance, entropy, etc.)
  • The relationships of pixels can be studied for emerging patterns
  • Motion, movement, direction, express change and additionally provide effect, narrative, meaning

The Organization of Pixels
  • The organization of pixels may be determined at a higher level: that of the image
  • Patterns in the organization allow for other forms of re-organization: compression, 2D edge detection, watermarking, and other forms of image processing.

Experimentation Approaches
  • In a given cluster of pixels, all of the possible combinations may be vast, but finite: John Simon artist
  • What may be interesting methods of exploring transitions between order and randomness (Markov, Ising, etc.)
  • What may be compelling patterns to surface based on pure experimentation?
  • Have all the rules of organization been explored?
