Joining Simon on the WPF quest

As Simon mentioned in his last post he felt that it was time to get started on learning WPF, I have decided to join him on the quest. So as of today I will be assisting him in developing the Point Case Estimation application as an XBAP.

Having used XAML in my last project I am sure that seeing the following will not freak me out too much

   1: <Path x:Name="DiamondShape"

   2:       Data="F1 M 256,32L 352,32L 416,192L 352,352L 256,352L 192,192L 256,32 Z "

   3:       Opacity="0.9"  Stretch="Fill"

   4:       Stroke="#FF2A8117"

   5:       Fill="White" >

   6: </Path>

Can anyone actually tell me what “F1 M 256,32L 352,32L 416,192L 352,352L 256,352L 192,192L 256,32 Z “ actually means without a some sort of reference guide? Maybe Chris Sells might be able to help me much like he did with Scott Hanselman

I guess that is the ultimate challenge.
