I'm a little bit stumped on how to make this feature work...
I've got cards are flipping the way I'd like them to (Thank you GSAP!)
However I want to add the functionality that if a card is already flipped over and the use clicks on another card's 'view' to flip a second card over... I want the first card (that is already flipped over to it's back) to play in reverse (and go back to its starting position) and then the second card can flip over.
Much like this: http://www.google.com/landing/now/#cards/
Any help is GREATLY appreciated, as I can't figure out the proper way to achieve this effect. (you can see I get stumped at line 42 of the codepen)
