Some crazy kids have come up with the bright idea of turning London into an urban playground for those who are looking to relive their childhood. The Hide and Seek Festival was founded by Alex Fleetwood and Gideon Reeling, after attending Come Out and Play in New York.
According to their website, "Hide and Seek is a festival of social games and playful experiences... it will encompass everything from fine artists making location-based work to huge flashmob games within the public spaces of the Southbank Centre".
Games include "This is it..." which requires players to race across the city to rescue a special-guest band in time for them to play a gig at the festival's opening party, and "Snap-shot City" which sees New Yorkers and Londoners on a worldwide photographic treasure hunt.
Check out this short documentary about the festival last year:
Get ready to join in the fun this weekend June 27th - June 29th...I can think of worse ways to spend a weekend.
