Momento, flashing forward into the past

I recently watched the movie Momento. This movie utilizes flash forwards that technically are also flashbacks. The plot line is very unique because it begins at the end and works its way to the beginning. During the movie Guy Pearce plays the role of a short-term memory impaired man named "Leonard". Leonard takes pictures with his polaroid camera and makes vital notes as the day progresses, some notes so worthy of remembering that he has them tattooed all over his body. The movie flashes backward chronologically, but forward into the plot development. This was an amazing movie and I really recommend watching it.
