The original version of this book contained holograms from the vendors and many of them are no longer in business. Therefore this version of the book contains everything that was in the original version but it has no holograms.Hold the hologram in front of you and slowly tilt it from side to side. You can see around each side of the image! Now, slowly tilt the hologram up and down. Watch each of the "televised" images change! Look closely at the hologram as you continue to move it around to see additional visual effects.
