So in getting my MacBook setup over the last few weeks, I spent some time looking for a good wallpaper. At first I thought I'd just throw up a collection of photos from Top Left Pixel and let them rotate. That worked, but then I came across OS X Planet. Complete geekery, but I think its pretty cool to be able to see at a glance roughly what time it is anywhere in the world and check out the current cloud systems to see what's up.
Yeah, I know... I'm a geek.
