Pepper's Ghost and Half Mirrors

[MusicFestival]

Has anyone saw the patent Disney has for a pepper's ghost using a half mirror? Rumor has it that they are going to use it to make a cartoon Tinker Bell fly around in a room. Just wondering if anyone has saw it, and how exatly they're doing it...I'm not very familar with the use of half mirrors.

Here's the link to the patent...
