Negative Buffer Values

A while back the question came up if anyone used negative values to create a buffer in another forum. I thought WHAT? Most of  the buffers I create are with point or line type objects, if you do a -10 distance buffer of a point or line object what do you get? Nothing! However you can create a negative buffer from a polygon object. Michael Schlosser from  the Autodesk north of the border team shows how to use it and provides a good example of why you might want to here on his blog.
