Those are really cool. The first one looks like it’s getting darker (stating the obvious, I know), I probably would never focus due to staring into it if that was my background.
I would post my desktop wallpaper, but I haven’t one, I use a solid colour (Windows classic blue [which is ironic considering I’m running LUbuntu]) and it has no icons on it because I use the quick start buttons on the task bar and the “Start” menu if one can call it that when running Linux, and I have that auto hiding, so when looking at my desktop with the mouse not near the bottom of the screen, it’s just a blue screen.
