This was posted by ReUseConnection, it just blew my mind. I love it. This couple, Michelle and Nathaniel Stitzlein, have a studio in Baltimore Ohio called the Art Grange. They both make sculpture, and also computer graphics. Michelle reuses many objects in her beautiful sculptures, such as piano keys - they exhibit their art, and also hold workshops for children where they make mosaics out of bottlecaps. This is their website: http://www.artgrange.com/. I always wanted to make art out of bottlecaps, and other objects as well, in the past - these people are really, really doing it.
Michelle has published a book of their bottlecap mosaic projects with children - which would be awesome for schools (or home art projects).
I've started saving bottlecaps again.
