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? <a href="http:&#x2F;&#x2F;glitchclub.com" rel="nofollow">http:&#x2F;&#x2F;glitchclub.com</a>

that might be a safari bug on iframe. When open it without the iframe, it works on safari, link: <a href="http:&#x2F;&#x2F;codepen.io&#x2F;wentin&#x2F;full&#x2F;doYyrj&#x2F;" rel="nofollow">http:&#x2F;&#x2F;codepen.io&#x2F;wentin&#x2F;full&#x2F;doYyrj&#x2F;</a>

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

Not working in FF 37.0.2 either.
