Decorating my iPad

Receiving an iPad was like a early Christmas present to me. It has so far been good having it with me on this week's trip. Was given a few stickers from the festival. Since all students will have the same colour and type of iPad, it will be hard to distinguish whose who. As we are allowed to put stickers on, why not put these science related onto the cover? Shame there is no stickers for nutrition related topics...
