Japan: cool man hole covers
Many public works projects in this country turn out really nice. I have to wonder where they get the money for all of them. For example, every sidewalk in the big cities has a strip of specially textured tiles to aid the sight impaired. It makes it easy to tell when you have moved off the straight path. Additionally, it is great for those whose attention is 100% focuses on their cell phone.
Take a look at some of these man hole covers. They are works of art.
