cool cool cool *science

I can't explain it . . . but they can:


<Protrude, Flow> uses magnetic fluid, sound, and moving images. Affected by the sounds and spectators' voices in the exhibition place, the three-dimensional patterns of magnetic fluid transform in various ways, and simultaneously its flowing movement and dynamic transformations are projected on the wide screen.

The magnetic fluid appears as a black fluid. It is made by dissolving ferro magnetic micro-powder in a solvent such as water or oil, and it remains strongly magnetic even in the fluid condition. Therefore, it is more flexibly transformable than iron sand and so it is possible to create more complicated three-dimensional organic patterns. That appear occasionally as pointed mountains or pliable organic shapes, sometimes as flowing particle streams.

The transformation of magnetic fluid is caused by the interaction with environmental sound. The sounds in the exhibition place (sounds created by artists, and voices of spectators) are caught by a microphone hanging from the ceiling, and then a computer converts the sound amplitude to electromagnetic voltage which determines the strength of the magnetic field. At the same time, the magnetic fluid changes its three-dimensional patterns sequentially. Each pattern appears synchronized to the environmental sound and the points of the shapes move correspondingly. As a result, magnetic fluid pulsates according to the sound. A digital video camera captures images of the moving magnetic fluid, and projects it on the screen.

Thanks dag!

Why am I no longer privileged? Is it because I already promoted this video? I've been away for so long I don't know the "rules" anymore.

Thanks dag! And Woland for the try

Cool stuff, upvote, but the way it's silent for so long and then sound kicks in at about 2:14 is very creepy. (or did I just have an audio malfunction?)
