The bicycle barometer takes data about the weather, the status of the tube lines I use to get to work, and whether my local station is open or shut.
It then reduces all that data down to a single value and displays it on a dial with a bike sign at one end and a tube sign at the other.
For example, if it is raining a bit the dial will move a bit towards the tube sign, but if the tube is suffering delays, it will move a bit back in the other direction.
Different data points get different weightings. E.g. snow is more important than a bit of drizzle; the tube station being shut trumps everything.
(I’ll make the code available once I’ve cleaned it up a bit, follow @richardjpope for updates.)

The economy expanded just 0.4% in Q4, a 2.3% through the year pace, marking a fourth year of sub-trend growth. That streak looks set to end in 2012 on the back of the ever-impressive mining project build-out, which will also underpin growth in 2013. In the meantime, our view is that monetary policy should be eased a little further to take account of the cyclical weakness in many segments of the non-mining economy. The unemployment rate will be the key variable guiding policy.
