I spent the day doing this. It's the first time I've edited a photo and customized an interface.
Although it's simple, I'm happy with the result. What do you think?
I used GIMP, KLWP, a wallpaper from another thread, and random icons from the internet.

The buttons are not real KLWP objects but are part of the wallpaper I edited in GIMP... But I added real buttons in transparent color. ¯\_(ツ)_/¯
