The beauty of Andrew Mayne's GhostVision is that you can borrow anyone's phone (that has a camera)
and create a miracle. Whether you use it to reveal a person's chosen card or to expose a ghost in
the background (my personal favorite), your audience will be blown away. They walk away with a
memento of your performance on their phone that they'll be talking about for weeks. It takes a
little boldness in its method, but its easy after you get the hang of it. This is something you can
carry with you and do anywhere on the spot. You'll have to get familiar with a few of the different
types of cell phones out their, but once you do, its as easy as saying cheese and snapping the
picture.
