At the request of another developer, Mikko Koppanen has written up a post for his blog today showing how to create animated GIFs in PHP with Imagick.

Today's example was requested by a user called Devo. This example illustrates making an animated GIF image by creating the frames from scratch. It's been so long since I've really drawn anything so I decided to use text as the base for this animation.

His example ends up as a string ("Hello World") that's animated to show one more letter at a time as each frame loads.
