QS Favorite Show and Tells

I’m making my way through the wonderfully extensive Vimeo QS archives http://vimeo.com/groups/quantifiedself/, and I wondered if anyone might be willing to share favorite Show and Tells you’ve seen at QS events. Any presentations that really resonated with you, suck with you, or informed your own QS experiments? Just hoping for a different way to filter the archive that is richer than scanning based on accumulated views and likes.

Thanks, guys!
