As a routine UX exercise I brainstormed for how an interface could be build for an (for now) imaginary 10,000 floor elevator. I came up with a number of different ideas out of which the top 10 are listed in the form of wire-frames. 

A common notion will indicate that a building with such a large scale elevator will have all the type of services in the world ; From residency to entertainment and offices. I focused mainly on how a very busy individual will process the system of interface within seconds and will be able to complete his task i.e. reach the correct floor. 

Working principle: "Less is more."
