This is sound visualisation!
Artist Kim Kichul is obsessed by sound and creates sculptures and installations that materialize noise vibrations. Results are awesome!
Did you also see human beings dancing at 1:58? There is not much description accompanying the video. The installation looks pretty simple: speaker at one end, a plexiglass tube close at the opposite end and specific sinewaves. Amazing!
If you like Kim Kichul‘s work, he has many more sound videos on his Youtube account. You will find information about some of his installations on the center for integrated media‘s webpage.
Watch another mind-blowing visual representation of music in this cymatics video!
