Physics of Dreamtime. This is a paper I did on the the Acoustic properties of a didgeridoo.
You can view the .pdf file of the project and listen to my not-that-great audio samples.
To play the audio samples you will need an up-to-date version of
Quicktime or some other mp4 capable player
(just get quicktime, its the best thing out there.) To read the paper you will also need
Adobe Acrobat Reader.
