A little over a month ago I came across this article about using Star Wars voices (Yoda, C-3Po, Darth Vadar, and eventually Han Solo) to give directions through GPS devices. It really is a pretty fantastic idea. As it currently stands, I almost always turn the voice off on my GPS because I find it annoying and less than helpful. Anyway, when I originally found it I shared it with a few close friends, but wanted to share it with a few more of you now. So, if you want to read about it, follow the link above, but below are some videos promoting the voices.
