To get to the other side

Although there are no definitive studies, some research suggests that pedestrians crossing streets are at greatest risk when obeying signals in crosswalks, and that careful jaywalking may be a safer way to cross the street.

I'm naturally a little suspicious, but Greater Greater Washington makes an interesting point:

Most research on traffic safety focuses on narrow questions posed by the highway agencies that fund it. Basic premises, like the idea that "jaywalking" is intrinsically unsafe, are rarely investigated...
One useful data set was collected for New York's Vision Zero program. That city, where residents routinely ignore signals when they cross streets, can be thought of as a natural experiment. The majority of pedestrian deaths, and a far larger majority of non-fatal crashes, occur while crossing the street legally in a crosswalk.

I doubt the data really addresses the relative death rates associated with jaywalking vs using a crosswalk. But still, it illustrates one of the hard realities of managing the interactions of cars and pedestrians (or bikes) - no matter who was in the right, the person who isn't in an armored, high-speed vehicle usually loses a confrontation. 

The National Mall

I went down to the Renwick Gallery in DC a few days ago to see the exhibit WONDER, which lived up to its name. While in the area, I got to listen to the album/app/experience "The National Mall" by DC-based Bluebrain. 

In the physical world, the National Mall is a wide expanse of open space anchored by the Capitol building to the East and the Lincoln Memorial to the West, surrounded by iconic Smithsonian museums and US civic institutions. The National Mall is also location-aware musical composition, a self-contained iOS app that uses your GPS to determine your location and only plays when you're on the Mall.  

As you walk along the Mall, the ambient soundtrack shifts to reflect your changing location, blending seamlessly from one locale to another. The promo video includes some of the musical tracks in their appropriate locations. It makes for a lovely and immersive experience.
