A real-time map view on almost all cities around the world that offer bike hire schemes. Currently in London, as of 37 seconds ago:

169 Bikes in use
638 is the highest so far today
4037 bikes currently available in docks 

The future of the internet will be about matching up local supply and demand in real time. Zipcar is doing it for cars. Barclays is doing it for bikes in London. ZocDoc is doing it for doctors in America. I think this is only the beginning. And none of this would be possible if it weren’t for these schemes opening up their data.
