As part of the 2012 RHS Hampton Court Palace Flower Show in London, landscape and design consultancy The Edible Bus Stop conceived of a green space that incorporated gardens, artwork, and the conversion of a street into public space. The temporary exhibition titled Riot of Color was conceived as “a post apocalyptic interpretation of the after effects of the 2011 London riots.” One of the more novel aspects was this fun park bench designed as yellow street lines that rise from pavement to wrap around a tree.
