Great article!  I was wondering if the Coding4Fun team would (or could) do an article on the TransformSmoothParameters?  Any article or documentation kind of glosses over this area.  The best resource I've found to date is: http://cm-bloggers.blogspot.com/2011/07/kinect-sdk-smoothing-skeleton-data.html But even this doesn't really explain whats going to happen if you change specific parameters, or give examples of when/how to change these for given scenarios.  It can be a little frustrating to constantly be told to just 'play around' with it when we don't really have a solid understanding of the components we are playing around with.  Settings for one scenario don't work for another; while I can tweak the settings to work with the new scenario, I don't know WHY they work.  Any help would be appreciated!
