This is a render that I prepared for a presentation I am giving at this year's FlashBelt (flashbelt.com).
Here, we see a clear example of what I call 'bridging behaviour'. Though individual traders are limited as to how far they can 'see', colour groups often form 'trade routes' allowing them to trade over much longer distances. This is not specifically programmed behaviour, and indeed was somewhat surprising to see.
ABOUT THE COLOUR ECONOMY:
What if pixels were free? What if they could trade their computer-given red, green, and blue values in pursuit of a profit?
The Colour Economy imagines an artificial economy of pixels, in which individual 'traders' exchange colour.
The Colour Economy is a project by Jer Thorp (blprnt.com) and was built with Processing v. 0135.
