Modulo

This little piece of art is called "Modulo". It's not a photo, but I found it pretty, so why not sharing?
Images that represent basic mathematical operations, isn't that some kind of a contemporary art cliché? The modulo operation computes the remainder of a division. In this case I divide each pixel's X and Y coordinate by a fixed value and encode the remainder in the same pixel's red and green value respectively. The fixed divisor determines the size of these squares and the modulo the color gradient. The more appealing way of debugging programming code. However, sometimes you just don't know if it's your eyes or your code that needs to be corrected...
