Swedish artist who initiates interventions into urban spaces and questions the uneasy co-existence of public and private territories - is such a delineation legitimate?

Produced a series of negated advertising posters, focussing on the commercial use of public space - coating hoardings in white paint - a thick accumulation of propaganda - providing a blank canvas for passers-by/public to work with.

Her aim is to 'divert materials or spaces from their prescribed functions, inventing ways of making these things improper again.'

Sometimes her exploits are unseen and anonymous (e.g. free postal delivery service) and in recent years her attention has increasingly focused on art spaces - for the Nordic Pavilion at Venice she recreated a teenager's bedroom (that tension between public and private again).

In 2002 she conducted a raid on downtown Stockholm, removing posters from walls and bus shelters, leaving small stickers ready U TRY MME (a pun on the Swedish word for 'space')
