I'd love to see pictures of an exhbit at the Exploratorium in the later 1970's. It was the jaw bone of a whale, created into a Solar Harp... It set center of the Exploratorium, under a sky light to let the rays in (when the fog was shining..lol). An old friend, Eric built it and it was displayed for a long time.
Yes! You are talking about Solar Harp, aka Sun Harp, built by Eric Reiter. Here are some photos of the exhibit.
I had a friend, Eric, who built a Solar Harp from the Jaw Bone of a whale. It was center place during the later 1970’s (I remember 77-78 it being there). A skylight let sun rays down to the floor, as the sun rays hit the harp, it would play wonderful sounds… I wish I had picture….
