Show HN: Color drop animation

Cool effect, but does not seem to work on Safari (8.0.5, OSX 10.10.3)

Want to show it off on Glitch Club? http://glitchclub.com

that might be a safari bug on iframe. When open it without the iframe, it works on safari, link: http://codepen.io/wentin/full/doYyrj/

Nice. But it does not work on Safari. Ok with Chrome.

Not working in FF 37.0.2 either.
