To turn Bob around position the mouse arrow over the patient. Hold down on the left mouse button and move your mouse to the left or right. To get a closer look at Bob press the button at the bottom with a "+" sign. To zoom away from Bob press the button at the bottom with a "-" sign.
If the movie does not appear then you need to get the quicktime movie player. The quicktime movie player allows you to zoom up and get a closer view of the patient. However, I understand how difficult these players can be to use. If you can't get the quicktime player to work on the computer you are using click here for a version that does not require quicktime movie player.
