Just Look Happy:)

London's pavement in cluttered with commands;

<- Look Right.......... Look Left ->.......... <- Look Both ways ->

Strickt, Formal, but logical since you wouldn't want to be run over. Especially important for the tourist who are use to traffic on the right side of the road.

BUT.. I thought I cheer London up from this cold strict business! And give the world a new message; Look Happy!
