this is such a great idea!
it would be great to be able to choose a series of events (e.g. d-day or the Beatles tour in 1967) and see the progression of events across a map in the order they happened.
or to get a cross section of all the events that happened on a given date around the world or in a chosen area.
edit: after exploring further I realise some of this is already possible. again, a great idea!
