The wallpaper looks more to me like a movie poster, but I definitely wasn't going for that in the beginning. Must be the dramatic poses. Yes, that's it. I originally had ghostly water molecules instead of just the formula, but they looked like Mickey Mouse, so I yanked them back out. Hrm.
I'm actually fairly satisfied with this one and have stopped working with it. Now if I could only do the same for the wallpaper.
I, er, may have also made a new icon out of the same elements. Maybe...
