Though the Chicago logo has six points, there is something very bold, very American about it.
the Tokyo "knot" is my favorite but I am a sucker for Japanese design. This includes electronics and architecture. I will sometimes drive down to Little Tokyo in Los Angeles and walk through a supermarket there just admiring how the sake bottlers, or the food package designers take complex Kanji and make the characters look so readable, so minimalistic and so human.
I like Baku next.
