I got bored of the same ol' desktop and I thought that it needed some spice. I found a way to reskin the Windows GUI. I could've used the WindowBlinds program, but I had to pay for all the features. A better way I discover is through a patch. After patching, I went to find a theme that resembled Mac OSX. I went through a few of them and here's what I liked best.
I could've gone all the way and just done a complete overhaul of the GUI using FlyakiteOSX, but I didn't need some of the Mac functionality (e.g. Expose, using Dock as a taskbar, the menu bar). Along with a few other programs, I'm currently using a Windows-Mac "hybrid desktop." Do any of you with Windows run desktops with other themes?
CRZ's right -- they actually did this simply because it looks cool. Expose (the name of that effect) is supposedly one of Steve Jobs favorite features in OSX, so they did this to show it off. I forgot it even existed until you mentioned it, so thanks!
