Animated posts are easy!
I just made this #animated pin on Pinterest. When its url is shared on Facebook or GooglePlus, it only takes one click to see the animation and then one more click to visit your #ZazzleCollection (or whatever link you give when creating the pin).
It's a 25 minute project the first time you do it, 2 minutes when you get good! This is a sceenshot of the pin, click it to see the actual pin doing its animation thing :)
You can see how to do this for your Zazzle collection in this 6 minute vid tutorial:
