What's new
Hello, here's my ridiculous side project
An introduction to what I write, and why I write it, and where my strange new road sign simulator fits in to all this.
London, in a new light
It was specially designed never to be noticed. And now it's disappearing, nobody has noticed its absence. It's London's own bespoke street light.
The Ringways Map is here
The wait is over! The full map of the Ringways, London’s unbuilt urban motorway network, is now online. Not even the system's planners had anything like this.
Have you seen...
Junction Three
The M621 has one junction where everything leaves the motorway and heads for the city, and a very bizarre junction it is too.
