To get lost in the city is not as easy as it might sound. There are plenty of examples in literature and film of individuals straying from the path, ending up in the wilds and paying the price, but take a wrong turn in the city and all you have to do is stop the nearest passer-by and ask for directions (assuming you can find anyone willing to stop and talk). Getting truly lost in the city surely takes more effort and may assume a metaphorical meaning, involving a kind of blindness to your everyday practices.

With this thought in mind, I proposed yet another chance mechanism which is a familiar tactic of the dérive or drift, a method of wandering adopted in an attempt to defamiliarise yourself from habitual methods of navigating the urban landscape. Sometimes called an 'algorithm walk', it is characterised by a randomly generated set of repeated instructions, the idea being to break your normal destination or purpose-based motives for traversing the map - 'locomotion without a goal', and to heighten your receptivity to the psychogeographical aspects of the city.
