Brand Tags Game

This is more like a brand identity feedback turned into a game.  I think corporations would find this especially interesting to see what people think of them in a mass/anonymous way.  By default you are prompted with a random corporate logo and asked to input a word or phrase about it.  You can then view what others have also added, which is where the fun really is.  Another way you can play is to try guessing what company a tag cloud might be describing.
