During its two2-year 'Psychogeographical Survey of Glasgow' (1992–1994), the group concentrated on refining the interplay between the [[Lettrism|Letterist]] (and later [[Situationist International|Situationist]]) techniques of derived and constructed situations. The outcome, described in the essay "Programmed and constructed drifting; the event architectures of [[Unitary urbanism#:~:text=Unitary urbanism (UU) was the,International between 1953 and 1960.|Unitary Urbanism]]" (''Viscosity'' No.3 Glasgow, Jan 1994), highlighted the false separation between these two classic Situationist tools and their [https://www.thefreedictionary.com/indivisibility#:~:text=1.,bil%E2%80%B2i%C2%B7ty%20n. indivisibility] in practice. The techniques were initially borrowed from the constrained writing techniques of the [[Oulipo]], where the pure flow of an otherwise unrestricted ''[[dérive]]'' is directed in its apparent randomness (and given an element of control over its protagonists) by applying [[parameter]]s. The behavioral [[algorithm]]s employed by WNLA range from elaborate "drifting machines" that are carried across the terrain and deployed at regular intervals to generate recursive instructions for movement (non-linear feedback loops), to the simple "anywhere" hitchhiking sign, a regular sight in the summer of 1993 being held aloft on the westbound pavement of the bridge on The M8's Great Western Road.
Artist [[Ralph Rumney]] (1934–2002) is credited with bringing the workshop's activities to a wider audience. He was acquainted with many of the original Parisian Letterists and participated in one of the group's ''dérives'' in London in 1995. It was assumed that WNLA had disbanded shortly after releasing the fourth and final issue of its journal ''Viscosity'' (now infamous for being selected by the [[K Foundation]] to announce its 23-year moratorium on all artistic practice). However, the journal suggests that the moratorium applied to the K Foundation and WNLA itself, with the group committing to stop mediating their activities entirely until 2018.
