Guerrilla futures is a practice at the intersection of strategic foresight and tactical media. It's a direct answer to the challenge of bringing possible future scenarios to life in urban spaces. This is an edited version of a presentation made by Stuart Candy (@futuryst) as part of a panel on Urban Tactics, for the second annual Festival of Transitional Architecture (@FESTA_CHCH) in Christchurch, New Zealand, on 26 October 2013. The panel was organised by Barnaby Bennett (@mrbarnabyb). http://festa.org.nz/
