Google+ posted on Google+ a search tip to help you create and find pictures that were made into animated GIFs through their autoawesome feature.
You can search Google+ Photos for the word [motion] and Google will return pictures that have motion from you and your circles. You can also trigger the search at https://plus.google.com/u/0/photos/search/motion.
That is a pretty fun search, don't you think?
