A psychogeographer from Utrecht who developed walking algorithms, such as '1st street left, 2nd street right, 2nd street left' which are applicable in every urban environment and turn walking people into data-collecting computers. With the Psychogeographical MarkUp Language (PML), places can be characterised as closed, empty, distinct, at ease or lively. The processed data can "take the fingerprint of a city" and generate "a new mythology for urban space".
