Hierarchy

This is a picture of an ergonomic office design.  It demonstrates a few elements of hierarchy but first I'd like to ask you to ignore the man in the chair.  I know it's hard to do because he is one of two things in the photo that has some color to it.  Your eye is immediately drawn to the computer screens because the color is bright and vibrant.  The next thing you notice is the shape of the chairs support system.  It's a large shape that encompasses most of the piece and your eye will not ignore it.  I imagine that if this piece was being seen in action, there would be movement in the screen and from the mans hands.  Of course that movement would probably draw your attention before the shape of the support system.  These are just a few examples of how visual hierarchy works within this piece.
