The best layout of transitions and odd shapes I ever seen was in the USS Alabama battle ship. You walk thru and just look up, I'm talking basically the whole ship, everything is oval to hug tighter to the ceiling and then branches off into many complex shapes, all hand made I'm sure. If I remember right, there all small pcs, riveted together. First went there in the 70s" as a kid, then stayed on it overnight with the boy scouts with my own son it the 90s". Went back in 2005, my wife will never go again and says I'm crazy. Her father has made her go there several times as a kid.
