Dancing Colors


How does sound look like? How can you make it visible?
Fabian Oefner answered these questions with this cool project.






 He came up with a simple method to turn the audible signals of sound, the waves, into a visual signal. He mounted a thin plastic foil on top of the membrane of a common loud speaker, and then added hundreds of colorful, tiny crystals onto the foil. The vibration caused by sound coming out of the speakers causes the crystals to dance. Depending on the frequency, pitch and volume of the tone, the figures change their appearance. So now, the audible signal, the sound wave, has transformed into a visual signal …sound has become visible.


Here’s a cool video:
