The scene of Neo's Desk and office space transition into the cellphone (change of his life)
Neo's life is depicted boring bleak and lonesome as Thomas Anderson
compared to the home or living situation of the computer hacker Neo his apartment or place is erratic and untidy. As soon as the random package appears for Thomas Anderson his life is flipped upside down and the music and sound track gives us the feeling and rush of the changes taking place in the life of Mr Anderson
At this point in the life of Thomas Anderson is flipped upside down as mentioned earlier this picture is also gives off the foreshadowing of the real point in The Matrix of which Morpheus (character) the real purpose of The Matrix just the look of the cubical alone seems to depict a prison like feel to it which Morpheus reveals later.In this shot Mr Anderson appears to be in a stasis type of moment again prison reference.
As for the sound track especially the iconic sound that plays just after the phone rings this iconic sound I automatically associate with the film.
