Hi guys, so I noticed this new Tumblr 'like' animation (although it was around a few months ago) on the dashboard. Anyone know the tech behind it? I want to implement it to some of my projects. Thanks Here's the gif http://media.tumblr.com/4e16fe3161714c52a91c3dcc2b7a8261/tumblr_inline_mnoaselA2C1qz4rgp.gif

Webkit only: http://jsfiddle.net/nWKfr/1/ It's in the css files, so it is very easy to extract it.
