Some people do crossword puzzles when they're bored. Some people knit. I redesign my website. Actually, I stole the theme from another website and added my own header. It's not a trivial task, but nearly as complex as the one I gleaned from, which was an enhancement of the default theme.
Anyway, let me know what you think of it. I created the header using a combination of The Gimp and Inkscape. I find that these two graphics tools, used together correctly, can create some very impressive artwork.
