This is one of my favourite tricks from David's Up Close and Personal book. Penguin have done a
great job on the decks you receive and the packaging. The tutorial is brief but covers everything
you need. There's a lot of very clever thinking built into this trick that allows you to concentrate
on your presentation whilst blowing your audience away. It's a shame different performance footage
wasn't used - the muted reactions and slightly hostile participants in the trailer downplay the
power of this hard-hitting piece. Craig Petty has a performance on his channel that gives a better
reflection of what to expect (ie people going freakin' nuts!)
