"Phononic materials are engineered media that can manipulate waves propagating through them due to their synthetic and periodic architecture" Got that? My rough understanding is how soundwaves move through materials, and how soundproofing works.
Illustrating sound waves was pretty straightforward, with waveforms. Soundproofing materials was trickier. I looked at maths-based art (as that formed the exciting logo) with all its geometry, tesselation and symmetry, and the two parts came together nicely to carry the theme of the event. But where does the sound come from? These are the questions, and that's when the train the visual whoosh came in at the beginning.
