Flags make for great animated GIFs- I spotted this set of flags in Cookesville Tennessee, a US flag at half mast and a MIA flag. The first one is only 2 frames, the second 4. I was not even planning to GIF these, but the camera was in the mode of rapid fire shooting. And the light was good in the morning.
These were done in same fashion as my other photo gifs- import as stack into Photoshop, use its alignment option, and then monkey around in animation window.
