Upside-down maps

I love looking at maps which show familiar things in new perspectives. Here are some good ones:

Upside-down map of the world. After all, nothing determines what is up or down on a sphere.

The english north/south dividing line.

And a map that proves that Paisley is the arse of Scotland.

There are some more interesting maps at this guy's page.
