I ran into a post by Jennifer Van Grove at Mashable the other day that piqued my interest. Van Grove wrote about an application by Spotlight Mobile called Meridian. It gives iPhone users a way to get their bearings, like many other navigational apps. But it doesn’t just tell you how to get to the store or attraction, it shows you where you’re going inside the building.

Obviously, this isn’t nearly as necessary when you’re going to the convenience store (now why did they have to move the pretzels? How will I ever find them?), but for larger buildings, I think it could be very useful. According to Spotlight’s Web site, the company is working to partner with organizations that want to help customers and patrons navigate large areas. The app just launched and has only one location to choose from. As it happens, it’s my favorite bookstore on the planet, Powell’s City of Books in Portland, Ore.
