A few quick picks below in case you're in a hurry - otherwise navigation is on the top left.
Click the thumbnail to see the actual (large) animation. If you're on a smartphone, add this site to your home screen and then you should be able to just select an animation and add it to a text message via your phone's handy "add image" function. Be sure to use the large animation - not the thumbnails -it'll resize to fit and look much crisper than a blurry thumbnail.
