An exhibition of "talking stones" at the Palais Royal in Paris, just outside the Louvre Museum. There were several stones and they would strike up conversations amongst themselves. Very cleverly done with the projection on the stones which really gave believable facial expressions.
I was sort of reminded of them when I was in Chicago last January where they had these talking walls in the Millennium Park.
