I just stumbled upon this and thought it was so cool. Dentsu is a creative design firm out of Tokyo working on a campaign for some Canon printer. They teamed up with photographer Linden Gledhill to create a series of images that are essentially paint sculptures created from sound vibrations caught in time.
To do this, they wrapped a small speaker in a membrane, placed a couple ink drops of paint on and turned the volume up. As the sound waves moved through the membrane, the ink began to dance. Using both high speed video cameras and still cameras, they captured the amazing visual display of different sounds and vibrations.
I think it would be even cooler if they could somehow get the ink to freeze. Nitrous anybody?
