Photographer Fabian Oefner has created this really interesting series of photos entitled "Dancing Colors" with an idea to bridge the acoustical and visual worlds.  While the concept is not new by any means the execution is very good. Here is how Fabian achieved these beautiful photographs: "I attached a microphone to the speaker, which is connected to the flash system. As soon as the speaker emits a sound, the microphone picks it up and sends a signal to the flashes to trigger them. I took the images in a completely darkened room, so I can just leave the shutter open for a few seconds, only the event illuminated by the triggered flash is captured."
