I'm no professional at photoshop but I have attempted at my own Spongebob theme. The icons don't really represent what the app is about but it looks quite nice. The icons consist of 23 different expressions. For the download below, I have only added icons for my apps but if you want an icon for one of your apps then simply go into the 'Faces' folder, pick a face that you like, copy it into to the 'Icons' folder and rename it to the app's name as it is written on the springboard. Currently, there is no dock image so please feel free to improve if you feel you can. If there is already one like this, then I'm sorry.
