Allow me to present Blubuntu, my Blue Ubuntu desktop.
I use a customized Clearlooks desktop theme with glossy window border and the standard Human icons. For the wallpaper I use Hardy Blue from www.gnome-look.org. The calendar is Rainlendar2 Lite. I've used Ubuntu since Feisty Fawn. Now, I am using Ubuntu Hardy Heron, running on my HP 520 Notebook PC, Intel Core Duo T2300 @ 1.66 GHz processor, 1 GB RAM, 80 GB hard drive, and Intel 945GM chipset motherboard.
