Going underground... again...

Thanks to Menah Raven Ellison for the tip-off to the Fourthway website, which brings back an old friend. This used to be online a while back, but was then taken off.
It's an animation which morphs between the underground layout as shown on the map, and the actual position of the stations, so that the viewer can realise the distortion of the image of the city that one gets when using Harry Beck's classic map...
Try it and see what I mean...
