These festive roadmarks appeared on the street outside my flat this week. Dodging traffic, inquisitive looks from passers-by. One man asked what they were, no idea I said. Colours highlighting the texture of the road, maybe? Artistic scrawls by an obsessive savant, or a map of underground points of interest for the upcoming Festival of Tunnels? Crude guidance for low-orbit ballistics, or urban orienteering signposts.
Road works, anyway.
