My installation on St.Viateur street for Journée des bons voisins began with five rolls of receipt paper threaded through my writing desk and five or six chunks of graphite for people to do rubbings of their objects with. In the beginning I sat within the vicinity to invite passers by to participate and explain the process, but near the end I watched from a distance and was surprised that people had no trouble figuring it out for themselves. Not that it's rocket science, but through past installations I've learned that some people don't easily distinguish between a rubbing and a line drawing. Interestingly kids seem to figure out the process fastest.
It got longer...
until the wind got to be so much that I had to wrap the paper around the table legs.
I'm really enjoying having all this evidence of other people's objects.
