I was thinking a few days ago, what I should do, what I could create. I entered in some sort of a minor art block, when I took a look at my old design. One of them caught my eye. It was one of my old GIMP experiments. I couldn’t remember anything about how I made it, but it looked awsome, so i saw in this a challenge. Finally, I managed to remember and put back together a quick step-by-step tutorial.
