If you're snowed in, or just avoiding the icy roads and freezing weather, here are some ideas for passing your time. (Readers lucky enough to have more temperate weather might enjoy these all the same.)
- Think you know something about London transport? You can probably while away a good few hours on the London Reconnections Christmas Quiz - and there are even prizes!
- Draw a map of London: Londonist seeks entries for an exhibition in the Museum of London.
- Travel beyond the capital with the Unmitigated England 'Where's That Then?' photographs - answers are in the comments. (For the closest London equivalent, try the Guess Where London? group on Flickr.)
