I am one of those weird people who love to fall asleep to the sound of a thunderstorm (probably because I grew up in the lightning capitol of the U.S.) With or without the thunder, nothing relaxes me faster than the sound of rain, too.
So you can imagine how happy I was to discover this neat site that allows you to listen to rain and some nature sounds in various degrees of intensity. Move your cursor up and the screen and the sounds become lighter; move it down and you get the full roar of a big thunderstorm. I've kept the window opened but minimized on my browser and listened to it through my headphones while I'm working on the blog or e-mail, and it's very soothing.
I found the link over at diddlydarnthatcrapisnifty, which has some other interesting anti-stress sound and art generator links up for grabs.
