computer keys

My proposal is to take old unwanted computer keyboards and turn either the keyboards themselves into art or take the keys off and cover objects that could convey a message. many people in class suggested that we could use a chalk board and use the keys instead of chalk. Placement for this was originally going to be on the deck by bynum commons but i would like for it to be in downtown but i have no clue as to where we could place it. Cost wise is low most of the keyboards keys would be donated. only real expensies would be the glue/thumb-pins and or magnets and spray paint should we decide some need color.
