Cigarette butts found on the beach to make a giant clam? I bet it would be interesting but, yuck, the idea of picking up all those old butts.
It is amazing to think of all the art that could be made from left over stuff or forgotten trash.
I like the idea of using things from nature to make art. I once used wood chips to make a project called "past and present", and paired them with metal clips. It was to show the juxtaposition of natural things of yesteryear and the technological coolness of man made things. I used a light strip (of today) to separate the two and the shadows of the images were pretty cool. (I never really had to use trash as much as use things in our everyday life to make creations).
It was fun.
