Custom Wallpaper for iPAD

I am lucky enough to have received some iPads for my class this year. I am trying to keep everything very well orgaznized and working. I had to just use what was on the iPad to create the wallpapers, so students could identify their group's iPad. I've finally had time to figure out how to create custom wallpaper. I tryied this one out to put on my iPad. Love it---I can change it and then put whatever I want on the wallpaper. Now I'm in search of some good quotes to use on theirs.
