Johnson's latex and polyester sculptures were a high point in an event curated by Bob and Roberta Smith and the culmination of a design project on food systems in the town.
Here's artist Bob and Roberta taking it easy during the event - and yes he's one person...
...and here's a dish served up at the event that was created from fresh produce cultivated by a thousand new 'urban farmers' in containers across the town.
Over 6000 people attended the Super Market event; and the food project - Dott07 Urban Farming - was a great success.
On one level, it fostered new enthusiasm for growing produce in the town. The town's new 'urban farmers' plan to run the process again in 2008. Local government is planning to release vacant lots across the town for new urban food production. And plans are moving forward to create a new restaurant in the town that will be organized as a co-operative social enterprise and supplied by the town's new farmers in the future.
But the initiative wasn't just a success because it offered people an opportunity to grow stuff. It worked because it created a new opportunity for people to communicate - and it now seems no accident that the culminating event was framed by an artist.
the dawning of the society of extras where the individual develops as a part-time stand-in for freedom, signer and sealer of the public place.
He sees in their art a reintroduction of the idea of plurality
...inventing ways of being together, forms of interaction that go beyond the inevitability of families, ghettos of technological user-friendliness, and collective institutions on offer.
In Bourriard's mind, this is an urge towards creating new models of sociability.
In our post-industrial societies, the most pressing thing is no longer the emancipation of individuals, but the freeing-up of inter-human communications, the dimensional emancipation of existence.
More often than not, urban renewal and public involvement projects keep their creative and intellectual thrust hush-hush.
The sociability of public art also often plays second fiddle to imaging and market.
But it's interesting to start to see participatory design, art, social and economic renewal projects in the same frame as, say, Carsten Holler's metal slides at the Tate.
And be reminded that these projects are not just confirmation of how great it is to be alive, kicking and sociable. They are also microscopic opportunities to transform society step-by-step, spud-by-spud.
