The New York Public Library has created a fun and interesting resource for 3D aficionados. The library is allowing their online audience to create 3D images using archived stereographs.
This site is all about your participation, so have fun with it, experiment with it, and let us know how we can improve it. In fact, this project wouldn’t even exist if it hadn’t been for a user like yourself getting creative with library collections.
