Hot damn! I shouldn't have looked at that picture!
In response to Phreak:
Clearly Ki-Adi-Mundi is not a hologram, but is in fact a ghost. All holograms in Star Wars have the horizontal lines like an old TV set, whereas Ki-Adi-Mundi here looks more like Obi-Wan when he appears as a ghost.
And here's another spoiler:
Not only is Obi-Wan on the Jedi Council, but Anakin is too!
