the desktop background is so much fun because you can either use a picture you've taken or design your own graphics. I like to use photos that i took but you could do pretty much anything!
Step 2: ICONS
For Icons you can either just place them on the background or create a dock. I will be creating a dock because they are a lot of fun!! Make sure to create depth between the icons and the back ground because if you dont, the icons will just kind of blend in.
