From a complete newbie, I would like to create an animation in Blender 2.49b (Windows 7, 32 bit installation) of the the earth spinning in space, export to an animated GIF, and then embed in an HTML page on the internet.
You can create an animated spinning earth in blender. Add a sphere, add a texture of the earth (plenty of them with a google search), keyframe it rotating, render as an image sequence, job done.
