one request for my city - a rounded corner here and there in the construction of our buildings. ive grown up in a place where man-made structures are a collection rigid boxes.
as a counter-example, check out Casa Batllo or Casa Mila designed by Antoni Gaudi and build in Spain.
what you see is curvy, messy, interesting. thats what i love about the man-made structures in the lord of the rings. i suppose the non-uniformity is an indication of being hand-made rather than machine-made.
