Watch this video animation based on sine waves
Rain droplets form waves in a puddle.
Most of us know that sound can be broken down into sine waves. But Daniel Sierra took that knowledge and turned it into a stunning video animation for a thesis project called "Oscillate." He says drew inspiration from the idea that sine waves are the "building blocks of sound." The animation is great to watch, and the music is well done too. H/T Gizmodo.
