More on the Spectre

Images from this great Yoshiaki Araki thread. (If you're interested in tessellations and are twitterpated, he's a must follow.)

He links the Nature article (good and a free read).

Best one, so far:

And, of course, the actual article, by David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss.

Kaplan gives this illustration of the tile:

WAVES — Visualizing sound through cymatics and resonant frequencies | Phenomena - from ABC Science

Uncovering the geometric nature of soundwaves. This is visualized by directing sound waves through water and salt. The water rests in an upright facing speaker, and the salt rests on a high frequency mechanical wave driver. When the devices are activated with specific frequencies, the water and salt particles vibrate in synchronization with the soundwaves, forming incredible geometric patterns. Phenomena fuses art and science together to explore naturally occurring patterns, and the fundamental forces of nature that create them, to take us on an ambitious, innovative, and psychedelic journey through the fabric of the universe. Filmmaker Josef Gatti recreates nine ‘phenomena’ to produce mesmerizing art films, which are then paired with an original music score by Kim Moyes from Australian dance music duo The Presets. #PhenomenaTV
