If you could partially melt the city of London – then refreeze it: what might that new city look like?
Alternatively, if you could build a huge machine, a landscape printer, and feed molten rivers of the city – a new Thames of liquid windows, old domes of churches running like paint – through its cavernous gates and printheads, what might you actually print with it?
Could you use the molten city of London as an “ink” for future cityscapes – store it in a vat, and print new continuous bridges, endless architecture, from Kent to northern Yorkshire? A diagonal ribbon of liquid London, solidifying across all of France.
