f.lux is awesome. I use it too, mainly due to the somewhat inadequate lighting in my room. My laptop screen doesn't bother my eyes as badly.
On another note, right now I've got that random "Believe" picture someone posted on a different thread. Don't remember where, but it caught my eye and looked neat.
And yes, just cleaned up my desktop a few minutes before uploading it. It's generally got 5-10 icons scattered across the screen in random locations.
