I belong to an 8 part harmony group and part of a women’s quartet and I purchased a Digital Voice Recorder this year. With this new recorder you can upload your practice music to the computer and then to a CD (still working on the CD) but as I was working on my music in front of the computer I clicked “whats playing” instead of the library and what a surprise I had. The music and vocal were making wonderful patterns and colors on the screen – got out the camera and started taking pictures. This is what I got.
It was so fun to watch the patterns as I was working on the words.

Wow Sandy, what beautiful pictures. I can see them now as quilts! What an interesting idea for you.
