I have seen this thread, but today was the first time Ive opened it.
Very nice! Thanks for posting.
Now that you've sampled, there's a link near the bottom to all previous posts (although the first few are rudimentary and rough, as I was climbing the ol' learning curve). But they all have descriptive titles, so you can pick whatever interests you. If flattened cities are compelling, try #13: it's Sodom and Gomorrah, but I forgot the title!
