A CodePen by Eduard Mayer. Twitter Widget Rebound - Here's the example code for the Rebound "Another Twitter Thing" by Davey Heuser.

Sadly, Googles Maps API v3 isn't displayed correctly here on CodePen. Nevertheless, the animation's working pretty well!

So please view this Pen on GitHub (you can also fork it if you want :)): http://vsxed.github.io/Twitter-Widget/

It's working correctly on WebKit-based browsers. Firefox seems to crack up the animation, dunno why. Best viewed in Chrome, Ladies and Gentlemen :)

Have fun!

Specs:

- CSS-only, 
- gpu accelerated animations (yes, it also works on Chrome for Android and also on Androids stock browser ;))
- Maps are draggable (view it on GitHub)
- SVG Image Masks are used
