Can you generate (or point me at) a listing of psychogeographical maps
(see http://art.ntu.ac.uk/mental/whatisps.htm) made of Melbourne,
Australia in the last 50 years?  A bonus would be a chronological
record of psychogeographical metrics/mapping/reporting showing
evolution of Melbourne's psychogeographical qualities over time.

Any related records/reports of Dérive activities (as per Guy-Ernest
Debord's 1950s situationist definition, see
http://www.socialfiction.org/derive.htm) conducted in Melbourne would
also be appropriate booty.

Using search terms Psychogeographical,  Melbourne, Dérive and
chronological yield some leads, but also some misleading finds.  A lot
of action in Europe and the UK (eg:
http://www.ivanpope.com/psychogeography/index.html), but a bit quiet
down under it seems; can you dig something solid up?
