Startup Idea : Get busy during Loading

Whether it is a webpage loading or an application, I wish there was something to do while I wait. This phone application will interfere during the loading period of another app/page and present you with something fun to do, whether an XO gane or a set of facts or new words of a forgein language to learn... anything that doesn't need much graphics (to save time or the loading app will be loading) or advertisements (the way to get money). You can choose what you want to do. We don't want to scare people with advertisements so it may be optional.
