Remember these? They're animated gifs. Once a primitive, but vital method of animating anything on the internet, these little creatures soon became obsolete as swifter technologies became available.
Now, largely thanks to social network sites and their avatars, the little movers are seeing a resurgence.
Used also to create web phenomena known as "memes", the animations usually feature a short piece on a loop. They can carry a message, or they can be totally pointless.
The London Olympics, of course, provided a plethora of fun for the gif animators who lurk online. Here are ten of our favourites:
Boris Johnson and David Cameron get jiggy with it at the Olympics Closing Ceremony.
