This is a little demo showing what we had prepared for our spainjs talk.
Unfortunately our talk has not been accepted, we will try again next year.
This demo is done with D3, a javascript library for data visualization, that shows how easy is to create a particle system with SVG.
It uses HTML5 audio API for realtime sound spectrum analysis, canvas and some lovely effects done with CSS3 animations.
We are Vizzuality, a small company that works in stories that matter. More in our website.
Music by Jeroen Tel / Maniacs of Noise, available here
Thanks to @BlurSpline for Audiokeys.js library and Mike Bostock for creating D3.
