Disappearing Girl Act With A Twist

Common trick is the gal is in a box, cage whatever and they throw a sheet over it. Pull away the sheet and the woman is either gone or changed into a tiger or something.

With this trick no sheet it thrown over the performer, she's in a glass box and after some magic incantations from the magician, she slowly fades from view. Then after a few more incantations, a tiger or something appears in her place, maybe even appearing from a puff of smoke.

The way it's done is you're not looking through glass, you're looking at a video image of the person / tiger, whatever, as the cube is made of video screens and the interior is lined with hundreds of cameras, the images from which are fed into a program to create the images projected on the screens.

So when the assistant gets in the cage, a real time video of them climbing in is projected as it would be viewed if it were simply a glass box, then the image is faded to the video cameras showing an empty box. The tiger is moved in, and that live shot is faded in.
