title: webcam background blur effect
body: <p>I've seen this effect before, where everything is blurred except the front most object in the shot.  it was possibly a flash or flex effect which worked in realtime with video and snapshots.  can anybody shed some light as to what this effect was called or point to some resources?
  thanks!</p>
  
  <p>UPDATE:  So it was the microsoft lifecam show which had this effect built in and can be seen here at the 2:11 mark:

  <p>not as clean as i recall, but that's what i'm looking for.  Any ideas how this can be achieved in a custom app?</p>
