Back in 2002 most of us were still on dial-up internet connections. Mp3 files took a while to download. Using tiny samples a music album was created in Flash. The tracks play back samples randomly and the whole album is only 238 KB. In 2002 the sounds would start instanly even on dial-up, while mp3s took minutes to download.
Tracks never play the same way twice but have a set length (more or less) and can be selected on the menu. If no selection is made after the first the tracks play through to the end
