This is Nautilus, a sculpture by Katie Hudnall. It’s made of reclaimed wood and filled with books that you can check out from the Indianapolis Public Library. It’s one of 9 unique public book repositories designed by artists for that public library system in a program called The Public Collection.
Users across Indianapolis who are drawn to them can find books inside. These sculptures are sharing stations that are both works of art and functional libraries. You can see photos of the other sharing stations at Colossal.
