Finally installed Yosemite on my desktop. It doesn't look quite as nice on my monitor as it does on my MacBook's Retina display, but it's still pretty cool. One thing I like about Yosemite is that parts of it seem to be influenced by Linux, especially GNOME. The folders, for example, look like some of the older GNOME themes. That's a good thing, because I always liked the GNOME interface. By the way, the background is a photo I took from an airplane above the clouds.
