You might find Amsterdam an interesting challenge then. Within the centre area (roughly speaking, the bit enclosed by the Singelgracht), it was planned, but they had in mind (paraphrasing) "the practicality of a grid, but the beauty of curved streets", and so there's a horse-shoe type arrangement overall and then a grid within that. The effect is that you can walk along a canal, not really notice the curving of it, and be surprised that you're facing 90° or more away from where you expected.
