An interactive installation exhibited at the Prague Biennale. "Invisibles" by biot(h)ing uses holosonic speakers to create sound patterns projected into an interactive space. These speakers isolate individual cones of sound, creating a counterintuitive experience for the visitors as they move through different vibrations of sonar projections. At the same time LCD Screens display streams of information as it crystallizes and becomes visible through pulses of dynamic morphologies of 3D Cells scripted in animation software.

These crystallized streams may also be affected by the physical environment through an interactive sensor field. At the core of the audio/visual/physical interface is an interactive sound-programming environment that alters conventional forms of musical composition through the incorporation of algorithmically based processes.

biot(h)ing is the research-design laboratory of alisa andrasek - creating and studying algorithmically derived structures in virtual and physical environments.
