If such a site existed

If there existed a site where you could enter a word and then the site would create a "flash" animation of that word made entirely of books that have your word in the title, how would that be useful?
I merely ask because there is such a site! (thanks Jesus tribe)

Actually having thought that this was fairly pointless exercise I've found they are fantastic for Title slides on powerpoint. The one I used for a talk on "Sex" makes quite an impact.
