Too good not to share. Go to this link to hear the NYC subway appearing as a realtime stringed instrument --you can play along, too, by plucking the "strings." Another great fun way to play with Sensory Alphabet elements line and sound!
Imagine this as an inspiration for an art quilt or art cloth. Subways don't exist in reality in my part of the world, so they hold a certain grimy glamour for me. Ideas are everywhere. Awareness.
