The Real Underground is a Flash animation about the London Underground that lets you:
1. Watch the Underground map morph into a "real" tube
2. View a street map overlaying the Real Underground map.
3. Compare the current map to Harry Beck's 1933 original.
The Real Underground was originally shown on TfL (Transport for London), but with their permission is reproduced here. If you're interested in seeing a version that shows the whole map, I'm working on it. If you find any bugs email me. Because the animation uses Flash, you can't view it on iPhones/ iPads.
