I don't post in this forum, but occasionally I come here to view some of the nice photography that you guys post. I just finished watching this TED talk and thought that it might be appreciated here. In the beginning it appears to be an over-explanation of connecting two photos, but as you continue to watch it gets more interesting. Anyway, just thought I'd share.

All the pictures he created are pretty decent but the last one at the watering hole......well done!
