What would a tree sound like if it could sing ?

This is the main idea of this project. In plain words, I'm trying to make a tree sing. A way to think about it would be this:
1.Get a slice of a (dead)tree 2.Get the tree rings 3.Unwrap the rings 4.Get the values and map them to sound



Simple as that. This is Work In Progress, so things might be pretty bad at this stage.
If you want to see a few steps on how am I doing this, see the Making of.
At present this sound installation was presented in The Strech at Goldsmiths College and at the Slade Technology Fayre in Slade Research Centre. More info on that in the Performance page.
