I’ve created a new wallpaper for myself, even though “created” is a big word. More honest would be to say that I’ve modified the colors of the regular wallpaper you’ve seen so often in my screenshots. I’ve essentially only changed the two shades of yellow into orange and red, respectively.
I don’t know who made the original, and I don’t remember exactly where I got it from. It came up in a 
search for abstract wallpapers, and I’ve just tried looking for it again using various search terms, but I couldn’t retrieve it anymore. It didn’t appear to be copyrighted, and there was no mention of any author on it, or I would have remembered that.
Anyway, here’s the modified one, and with the disclaimer that I don’t know the legal status of the original, anything I produce is always Free — as in “freedom” and as in “free beer” — so feel free to use it, if you so like.
