I usually change my layout on my LJ-versary on Aug. 3rd, but I'm going to be on my California trip, and recovering from same all the way up to that date.
So... I decided to fiddle with it today! And voila: a banner based on The Vegas Renormalization (BBT, Sheldon/Penny, of course). I went a little crazy with layers, vector graphics, brushes, and a glow script... but I like it. :)
