In fact, the grey background I used was supposed to be a placeholder, until I find a good alternative, which I haven't found until now. For my current background, I decided to get an image from my collection and do some editing on GIMP, mostly dithering and messing with a few effects. I have changed the colors around the website, like the link colors for example, to match the whole theme of the website as well.
