This summer the English Table Tennis Association have placed 100 ping-pong tables in London's squares, shopping centres, estates, offices and train stations. The campaign, named Ping, aims to get a million more people playing more sport by 2012.
So if you are in London and you fancy a game of outdoor table tennis then you should check out the Ping map. The Ping Google Map shows the location of all 100 table tennis tables.
The map sidebar has a nice feature that dynamically loads the nearest table tennis tables to the map centre as you pan the map. The listings in the sidebar also inform you how far the tables are from the current map centre.
