For a graduate school class I wanted to use image processing to convince my professor that the trees are trying to talk to humans. The joke sucked, but I had fun taking pictures of trees.
So I used to be a musician, marching band type. However, that knowledge is gone, so the largest struggle I continue to have is combining the proper notes to achieve a desired effect, like sad or happy.
I work on the idea for fun. I really like joshua trees and every once in a while I make an interesting song by accident. It's a work in progress...
