• Resizing a GIF way beyond what it's supposed to gives that neato-keen "block" look, much fun to be had there.
• GIFs can be compressed best if they consist of same color bands running *horizontally*. For this reason, I usually run a motion blur on any gradients (top to bottom blends) with the motion going right to left, at 200 pixels. (You can save 70-80% in file size this way!)
• Someone pointed out in my first effort towards this that you could do a graphic at half width and then use width= to make it bigger again, the results were pretty good.
