This reminds me of a novelty I created early on in my programming career. I wanted to recreate the color picker from Photoshop (I think version 4) on a webpage. This was several years before jQuery and "Googling" it would have produced meager results. After considerable effort and writing equally "elegant" code as the OP, I had a 256 x 256 grid of divs displaying my color picker. Little to no CSS in that bad boy, but a ton of javascript hex conversions. The page loaded soooooo slow and brought my computer to it's knees, but I was very proud of it. I did actually use recursion, but not to the degree I could have if I had more knowledge. The achievement was not in writing perfect and optimal code, but in having an idea and seeing it through to completion.
