Jimmie P Rodgers shows off and describes the thinking behind his new tattoo, which provides a crib for resistor code, symbolizes the rainbow queer pride flag, and is also five inches long and can be used to measure lengths in fractions of that measure. It was designed in Processing, and Jimmy's posted the source so that you can replicate it, learn from it, tweak it and share it:
So in summary, it's a resistor color code chart, it's a rainbow, it's a ruler, it's got both the golden ratio and Tao built in, and it was written in a programming language. So it's a meaningful tattoo that's also useful for me beyond looking great.
