Random text fade in and out in background of page [closed]

[lol22]

I have a simple question-based single-textbox search page ala Google. The searchbox is centred and the rest of the screen is content-free.What I'd like is for random search questions to fade in and out randomly around the search box/in the background.I'm struggling to get my head around how I can achieve this - there is probably someone out there that has already done it, but I'm also struggling to put it into words to search.If anyone could point me in the direction of where this has done before, or what I'll need to use to do it, I'd be very grateful.EDIT: I should add, support for legacy browsers is NOT important - I am welcome to new (but not bleeding edge) technology.
