Attention Mac users
So my roommate told me about this really cool program for mac os X called desktoptopia. If you're familiar with mac's you know that you can set the wallpaper to change every so often, and just choose a folder full of pictures for the mac to choose from at random. Well this program allows you to do the same thing except it pulls the pictures from the web. It provides access to a huge variety of different styles and adds a good splash of creativity to your background. If you have leopard, you can quickly save any backgrounds you like by opening system preferences, then background/screensaver and simply drag the wallpaper to a folder you'd like to keep it in.
It's pretty sweet. Oh, and they also have a beta version for PC's for all you stuck in the "windows" ideology. Here's a little taste of some of the stuff I decided to hold on to.
