The screen is redefined by the addition of two further dimensions which the page lacks: a temporal one, and the third dimension, the simulation of depth. New spatio-temporal parameters thus become possible.

On the screen, space is no longer flat, but multiple layers of textual organization become possible. The dimension of depth is added, foreground and background relations can be constructed, letters can be superimposed upon others, distance and proximity can be simulated. Writing becomes volumetric: letters can suddenly be viewed from all sides, from behind, below, above, they can be rotated and turned around their own axis like real objects in space.
