A document display system and method for enhancing the effectiveness of a user interface includes one or more tiles, a spatial modifier, and a variable display region. Document data of multiple abstraction levels is obtained and represented at one of the abstraction levels in a document representation within a variable display region of the tile. The tile can be spatially modified by position and dimension having a tile position and tile dimensions. Upon escaping a particular range of tile dimensions, the document representation alters the abstraction level portrayed therein.
