Stylistic Vice Variation
This is an easily labeled vice to illustrate pressure, squeezing, force, etc. Both the top and bottom parts of the vice can be animated to move up and/or down as needed. The vice can be colored to match your template's color scheme very easily. This vice has two sources of pressure: the direct forces are the two squeezing parts. The handle exerts force on both of the squeezing parts. So the concept message can be very exact (see the series example).
Also see Force 019 for an additional vice framework.
Customizing the Vice

PowerPoint 2007 options
Don't add any advanced formatting.
Don't use 3D.
Don't add shadows.
Gradients, patterns, and pictures
Gradients might be good to add because it will add the illusion of light and shadows, which will make the vice look more realistic. You can also import pictures into the large sections (the two parts of the vice that exert the pressure) if you want.
The two parts of the vice can be animated to move up and/or down using motion paths.
