Heheh. Someone else made the "Hello, Clarice!" comment when that pic was first posted a year or so ago... LOL!
I use the Meguiar's Three-Step system, although I changed the final step (#3) from the normal wax to their professional wax (#26). That one is much, much better, IMO. Longer lasting and shinier.
Those shots were taken of the X when it wasn't even clean per se, or freshly waxed! It was wet, even. When the thing is just freshly waxed, it really is insane how shiny it is... I'll take some snaps after the next detailing day.
