The iBookGuy explains how graphics worked within the memory constraints of the Commodore 64 and NES, and the Apple II and Atari 2600
At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data.
"The observers of this unusual visual stimulus reported seeing the borders between the stripes gradually disappear, and the colors seem to flood into each other. Amazingly, the image seemed to override their eyes' opponency mechanism, and they said they perceived colors they'd never seen before."
"...we see on the ground a number of spots of light, scattered irregularly, some large, some small..."

Goethe's Theory of Colors: example of a "research style" that has "played a crucial role in the history of physics", or "tedious heap of mythical, uninformed or impressionistic color anecdotes"? Learn more about "Goethian science", then miss the point entirely by viewing a PDF recreating his experiments photographically, or playing with his triangle online. [more inside]
i began cataloging the colors, and put the color list on the web. over time, the paint catalog turned into a web site.
Not settled after all partial genetic explaination of eye color. it's not one classic dominant/recessive allele a la the monk Mendel. three known + unknown genes involved, everybody's still beautiful.
