I've had Kodewulf since around 2000. Decided in the wee hours of the morning one day that I need a new nick and a domain that goes with that. And seeing as I was trying to change my career path from IT support to development I wanted something that showed the "coding" part. Hence the "Kode" part, and at that time I was using this wallpaper:

And "Kodewulf" was born.
