Oscillate – Daniel Sierra
This is already old news as far as internet-time is concerned but this video from Daniel Sierra is stunning regardless when you first see it. According to Daniel on his website,
My goal with “Oscillate” was to visualize waveform patterns that evolve from the fundamental sine wave to more complex patterns, creating a mesmerizing audio-visual experience in which sight and sound work in unison to capture the viewer’s attention.
Mission accomplished as you will clearly see in video below.
