Quoted from robotron:the lens is gimmicky. its just a lense reflecting an image from an upside down screen. like the old arcade games used to do.
still thinks its ok but its not like a hologram like the haunted house in disney world.
It's not gimmicky when it's viewed properly. This is the best video of what it looks like as a player seeing it,
