Someone needs to do a Google Maps, but for the past. For example, typing in "London to York" but you can select a period e.g. 1450s, and it would give you the likeliest route. That'd be great.

What with all the fibreoptic Internet cables on the sea floor I really think it's sad we don't have a film where a shark bites into one and accidentally uploads itself onto the web and starts eatimg people through their computers. It would be called WWW, vertically mirrored so it's like teeth.
