Here is Zack the cat, colored in a sudoku pattern. Well, not colored exactly, but color-shifted. You can still see the texture of the fur within the blocks. A sudoku needs nine numbers or colors or patterns. Doing nothing is one, I had two more from Color Shift, and three more from Horse of a Different Color. That makes six. Here I've added three more transformations to my palette, namely canceling the red, canceling the green and canceling the blue. That makes 9 transformations, numbered 1 through 9 and applied in a pattern based on a solved sudoku.
Here is the original picture, shamelessly ripped off from TTB at Blogospherical Ruminations:

My Dear Nerdistanian,
I do not have a clear understanding of the color changes. I know you are being very precise in your explanation, but there are too many words that carry no meaning for me in this context.
However, I really like the color coded Sudoku. It might be interesting to have one to solve that was in colors. Also, can you made each color a separate level and I still need dark lines around the 3 by 3 frames. I have developed some very complicated tactics in solving Sudoku, but it seems to make solving the easy ones harder.

The picture is about 400 pixels (dots) wide by 300 pixels tall. 400 times 300 is 120,000 pixels. Each pixel is represented in the computer by 3 numbers, one for red, one for green and one for blue. Suppose we have an orange cat-fur pixel: red = 200, green = 100, blue = 0. We switch the numbers for red and blue. Now the pixel is: red = 0, green = 100, blue = 200, which is a greenish blue.
The fur has texture, which means that adjacent pixels have different numbers, corresponding to darker or lighter orange. For example, one pixel might have red = 250, the next might have red = 200, and the next might have red = 150. After switching the red and blue numbers, the colors have changed, but the texture remains. The texture has been transferred to the blue numbers, but it is still visible to the eye.
Royalties, Dude. I demand my royalties. Next time you wheel on over, you'd better deliver or I'll bet yer ankle. And my bipeds will let me out of the house to do inappropriate things in yer saddlebags. Friskies, and plenty of 'em or else you bleed, Dude!
Zack can't type, so someone is negotiating on his behalf. That makes that him Zack's agent, which means that he has to eat 10% of the proceeds.
Mmmmm, tuna-liver!
Who sez I can't type, you miserable excuse for a biped?
Yer just trying to weasel out of yer obligations, Two Legs. You better cough up some mouse frags and Friskies the next time you ride that round footed beast over here, or I'll use that tailess hide of yers for a rug. I'll stuff you so deep in the litter box that yer grandmother's cat's uncle couldn't find yer furless corpse. I'll chew yer ankles off to the neck. I'll sneer at you from the pune'e. I'll shed on yer hair. I'll leave the room.
Don't try my righteous patience, biped.
