Painting with sound, awesome! The artist Martin Klimas splattered paint in different colors over the diaphragm of a speaker. Then turning the volume up, the vibration of the speaker sent the paint aloft in patterns.
South Korean Flag love the meaning behind it. I've also heard that the short and long lines along with representing the elements also represent the strong protecting the weak and the weak protecting the strong. Like the taegeuk, its all about BALANCE.
