As I am no doubt the last person to point out, Google Maps has added a street level view to (a few) urban areas. It’s the first Google app (besides Picasa) that I’m aware of that requires Flash, but it’s also (as fellow Be alumnus pixelknave points out) the first Google app to feature the Be Man:

Update: The Google Maps Man now has his own instructional video.
