Scroll the page. Go on, scroll it. And marvel at the way the new, perfectly static Sonos logo pulses — like sound is emanating from its centre, producing a pounding bass line.
This new logo has been produced for by Bruce Mau Design, and it's supposed to "advance the idea of the modern music experience". In fact there's no mention of the fact the logo pulses in the rationale behind the design, but folks on Twitter soon realised what happened as you scroll down the screen. So either it was designed that way or it was a happy coincidence. Either way, it's pretty neat (though possibly also slightly nauseating).
