A History of the World in 100 Seconds :: @godawful watch, then read, then watch again. Magical.

I missed History hack day but heard about Gareth and Tom's fantastic visualisation of wikipedia references over time: and having seen it I love it more. In fact I would advise watching it - try and work out what is happening - then read their Vimeo entry below, then watch it again.
Is wonderful. (Just watch out for Jerusalem...)

Their VIMEO commentary::
Many wikipedia articles have coordinates. Many have references to historic events. Me (@godawful) and Tom Martin (@heychinaski) cross referenced the two to create a dynamic visualization of Wikipedia's view of world history. Watch as empires fall, wars break out and continents are discovered.

This won "Best Visualization" at Matt Patterson's History Hackday in January, 2011. To make it, we parsed an xml dump of all wikipedia articles (30Gb) and pulled out 424,000 articles with coordinates and 35,000 references to events. Cross referencing these produced 15,500 events with locations. Then we mapped them over time.
