When designing apps or promotions for Facebook, it’s nice to have a layered PSD file will all the assets needed to quickly comp something up for a pitch or tech hand off. I know, you could simply take a screen grab of your FB wall or page but you’ll still end up in photoshop cutting, pasting, covering up unwanted graphics and moving pixel blocks around to complete a FB layout. But why start with flat art when you can get a thorough GUI layered photoshop doc for free.
The GUI theme is absolutely free and is released under the Creative Commons agreement. In other words, you can use it for all your FB projects for free without any restrictions or complaints. That’s not all. They also claim you can modify the kit as you wish. Enjoy.
