This guy, Christoph Rehage, walked 2900 miles in one year across China, from Beijing to Ürümqi, and took pictures of himself along the way.  Personally I think I could have done this in 4 months...but getting past that this time lapsed video of Rehage's face is quite amusing and I love the music.  For more information about his journey (he originally planned to walk from Beijing to his hometown in Northwest Germany), visit www.thelongestway.com.
