Here's a simple .gif I made after drawing pictures with my daughter. The more interesting portion here is how I went about making it using open source software and the windows-key+print-screen. Here's a quick explanation: I made a simple Anpanman picture in Inkscape using circles and handdrawn lines for the eyes, eyebrows, and mouth. Then I selected the facial features but not the head, and copied them to the clipboard. Then I pasted them and grouped them so they would resize together. I pasted the now shrunk copy into the left cheek and continued to do that for 5-6 iterations. Then I zoomed out and found a decent starting point. I zoomed on the smaller face for each frame, and simply saved a screen capture with the windows-key+print-screen. Then I opened GIMP and selected the open as layers option. After selecting all of the screenshots I made, they opened in a single file as different layers. Then I could crop the image to remove the rest of my computer desktop, and removed the layers that would show portions I don't want to see (like the document outline in inkscape) or that would cause the framerate to seem off. Then all you have to do is export as a .gif and choose the animation settings that you want. It's easy and it only takes 2 open source applications that most people already have if they do anything with open source software.
