No, you’ve got it completely wrong, I expect people to say. You idiot, it’s for blind people to know where the footpath ends so they don’t keep walking into the street without stopping. I say you’re not interrogating the site with a sufficiently critical eye.
I say it’s a minimalist critique on the commodification of modern life. The uniform repetition of Lego style blocks in the footpath symbolises the tyrany of industry over the natural world and the lack of diversity in the urban environment.
