So I started up Adobe Acrobat Reader and was offered to update the latest version of this:
The Atmosphere Player for Acrobat and Adobe Reader is designed to enable use of Atmosphere environments within a PDF document enabling the user the ability to experience a rich variety of interactive content, including three-dimensional objects, directional sound, streaming audio and video, SWF animations, and physical behaviors.Just what I always wanted, PDF documents that make noise! Also, what's the deal with "enabling the user the ability"?
