I'm fairly sure this has no useful application whatsoever, but it's kind of cool ...

This is how this very cunning little applet visualises brianruckley.com. The way it 'grows' the map once you've plugged in a URL is very pleasing on the eye - if you plug in the address for a huge site (like the BBC, say), you could be there for some time watching the map blossom. Thanks to Tom for pointing this out.
