Calvin points out an accessible sidewalk in Beijing
When visiting Beijing last week I noticed that many of the sidewalks have a strip down the side that has a specific pattern. I started noticing it everywhere and finally asked "why the strip?". I was told it was to assist blind people. With my recent interest in accessibility I started paying attention and found that not only do they have the strip, when the sidewalk changes or when it comes to an intersection, the strip changes from raised dashes to dots.
Dashes to Dots
I began to notice the strip everywhere and feel rather silly that I didn't notice it earlier and that I had not recognized it's purpose. Perhaps this is a common thing and I've never noticed it in other cities, but I was really pleasantly surprised by it.

As a side note, I also found that each bill of their paper money could be distinguished by it's size, something the U.S. could use some work on.
