Jason calls his weblog all London Tube maps all the time'. It's interesting, especially if you're into design. As Jason notes (and others with him) the new London bus maps are really easy to read and very useful.

(I've got to say, he also links to a letter from Satan which is well-intended by a Christian to provide an alternate perspective on Christianity, ie, from Satan's point of view. You may think it's in poor taste, but it is a fair statement of classical Christianity's view of Satan. CS Lewis, who was a great writer, did something similar with 'The Screwtape Letters'. I imagine Jason thinks this is a gas (and the music is corny), but I think it's largely based on correct theology, though mayb a little hokey.)
