It depends on how you do them.
Actually, I should say something about how the format has evolved. First, it was these public art projects, like the one in Portobello Road, with complicated technological settings and people on Zoom. Then it became simpler, with just a piece of paper around a table. Then there was one in South Korea during a biennale that used stickers placed on the floor, so you did not even need an artist. You could draw, remove, and redraw.
Now, in Nairobi, in the central library, which is actually the biggest library in Africa, we are preparing a large sticker installation on the children’s floor. It will be installed in July, for National Reading Day, and it will be about how to build a playground.
We already did the same visual assembly in St Vincent, and I now think playgrounds are a better focus than cities. It is very difficult to build a new city, but very easy to build a new playground.
In St Vincent, I went there with Alastair Parvin, who is a famous architect. He created WikiHouse and has built 30,000 self-built houses in the UK. He helped me formulate the correct framework for making playgrounds through visual assemblies in a way that would be super cheap to build and could be adapted to different cultures and materials.
The idea with playgrounds is that they become a reason for people to practise talking to each other. Playgrounds are multi-generational places in the city, and children rarely play alone, so there are always different adults around. Our playground design is very simple: just sticks, hammocks, perhaps other very cheap elements, and a place for visual assembly in the middle.
Then people can add whatever they want. In St Vincent, for example, they wanted to build a garden there, and also some kind of kiln so they could make ceramics with children and sell them, turning it partly into a marketplace. I do not yet know what they will do in Nairobi, but it looks like we may have access to the space in front of the library to build a playground. So people can imagine the ideal playground inside, on the sticker, and then go outside and start implementing some of it. They might invite artists to do sound installations there, or masks, or political manifestations, or whatever the group concretely wants.
So if you do these as permanent public art projects, like a playground, then of course they become a public statement, and whatever people create there can carry a message. But in order for that message to exist, the horizontal structure has to be in place first, so that people can actually come together and have tools to speak with each other.
