This amazing experiment is called the Chladni Plate Experiment, it uses a tone generator, a wave driver (speaker) and a metal plate attached to the speaker that is covered in salt. At certain frequencies the metal plate vibrates in such a way that it creates areas where there is no vibration, where the salt is then trapped, creating these beautiful geometric patterns. As the frequency increases in pitch the patterns become more and more complex. For more interesting science full of design take a look at Brusspup’s Youtube channel. (via Geddem)
When it comes to design without purpose, this thing takes the cake. This device, which doesn’t even have a name, is an instrument for the sonification of everyday things. Once something is mounted in-between the two ends, it is spun in a continual circle, where a high precision distance measuring laser scans the object, creating a silhouette of sound.
“This is a serious musical instrument. It rotates everyday things, scans their surfaces, and transforms them into audible frequencies. A variety of everyday objects can be mounted into the instrument. Their silhouettes define loops, melodies and rhythms. Thus mundane things are reinterpreted as musical notation. Playing the instrument is a mixture of practice, anticipation, and serendipity.” – Says Dennis Paul, the creator of the device.
