a dérive

In psychogeography, a dérive (French: [/de.ʁiv/], "drift") is an unplanned journey through a landscape, usually urban, on which the subtle aesthetic contours of the surrounding architecture and geography subconsciously direct the travellers, with the ultimate goal of encountering an entirely new and authentic experience. Situationist theorist Guy Debord defines the dérive asmode of experimental behavior linked to the conditions of urban society: a technique of rapid passage through varied ambiances."
