Weird art in the library

I had the opportunity to visit the San Jose State Library the other day. It was quite an experience,especially when I saw the secret door. In movies it has been seen when libraries have trap doors. A door that revolves around and it usually leads to another room. I was really excited when I saw this. I have always wanted to try one out, and I got that chance. Unfortunately, this trap door did not go to another room, which defeated the purpose. I left the library that day wanting to return again.
