Now this one I like and having seen it I kinda wish the others were the same, just done in different colours. They have built in the title of the movie which makes it almost appear to be part of the contraption. The occasional dash of red stands out from the image which makes you think of blood but is more likely rust from the iron Jigsaw would use to make his traps.
If you head over to the Saw movie website the image comes together from a animation of a hand moving pieces of a jigsaw until the image is complete. Obviously this is a reference to the jigsaw piece that John Kramer (Tobin Bell) removes from his victims skin in the movie.
The other three before this one are here:
