My current in Windows is Irefay Eteorma , and my Linux background is a really old tileable background that I got at propaganda.themes.org back in the day.
My current one is the tree moss. I love nature wallpapers, especially in the winter time. Over here in Canada, theres not much to do outside until the snow melts and it gets warmer!
At this moment, my desktop has a photo of my friends and I skiing, thinking about how badly we want to try to hurt ourselves on the jumps farther down the trail. My laptop has a photo of some strange-looking ice crystals in a stream I saw while snowshoeing. I'll probably upload it when I get the chance to look it over and tweak. Here in upstate NY, there's not much to do but ski and snowshoe in the winter. :-D
My current is Tokamak, oldy but goody
