An interesting app, which Bob Lang and Brendan Conway told me about. It visualises the orientation of streets at any location.
I had a play, and it's an interesting result, although the granularity of zoom means that if you zoom out to the the whole of Norwich, for example, you essentially get streets from every sort of direction and no preferred orientation...
