It's a long flight from Saudi Arabia to Le Cap d'Antibes or Monaco or London--what's a Saudi prince drowning in petro-dollars to do? Buy a custom flying palace naturally, so that no moment passes without the comforts of home. Saudi Prince Alwaleed bin Talal bin Abdulaziz Al-Saud spent $485 million on the custom Airbus A380, with interior and amenities designed by British firm Design Q. Naturally, there's an on-board garage, so that the prince can be driven right to the threshold of of the airplane's elevator. After arrival, he can retire to his master suite--one of five with king-size beds, and computer generated prayer mats which always face Mecca (one must always be humble); up to 20 extra-guests have to make due in sleepers that are the equivalent of first class. But the real insanity begins elsewhere on the plane's three floors: There's a concert hall that seats ten and has a baby grand piano; a boardroom with a holographic projector; and a full-size steamroom. The most entertaining perk is a "Wellbeing Room" which has a floor upon which is projected an enormous image of what the plane is flying over--thus creating a "magic carpet" effect.
