This is wallpaper created using Pony-Vectors's excellent Pinkie Pie Panic! SVG vector, which can be seen here [link] . Basically, I was experimenting with Illustrator's symbols capacities and I wondered if it could handle a really complex vector, with nested layers and various levels of opacity, so to run a quick experiment, I used this vector, which I'd downloaded some time ago. Turns out it can, and this is the result. Though it was just an experiment, it turned out so interesting that I decided folks might actually like to use it. So, courtesy of Pony-Vector, Illustrator magic, and some minor inspiration on my part, here it is.
