The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries . All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries . Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons . Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?

This video, by Semiconductor, is an artistic rendering exemplifying the dynamics of electromagnetic phenomenon happening around us and through out the universe. The animations are set to audio from VLF radio-wave recordings produced from real ambient sources such as weather systems, electrical storms, the Earth’s core, the upper atmosphere, and solar wind traveling to us all the way from the Sun.

In this iterated function system, a Möbius transformation is applied in succession to the white circle yielding the blue and yellow circles. The characteristic constant of the transformation remains fixed, but the radius of the white circle is decreased in each frame of the animation.

An ideal rotation around the point at infinity in the disc and upper half plane model of the hyperbolic plane







Rotation around the symmetry axis of 4th order in the disk and upper half plane models

A Moebius transformation can be used to transform the disk model to the upper half plane model of the hyperbolic plane.

Hyperbolic translation along the horizontal axis in the disc model, and along both horizontal and vertical directions in the band model

This is a hyperbolic tiling with right angled regular pentagons shown in the disk model and the band model. The animation shows how one model is transformed to the other using the complex map The points +1 and -1 get sent to +∞ and -∞, respectively, and the points +i and -i remain fixed.
