Perhaps un-intuitively, a 2D/3D continuous medium (i.e. a picture) is less expressive than a 1D discreet symbolic medium (i.e. a script). For example, the picture enforces a notion of nearness, of distance, whereas the script need not suffer such strictures (unless explicitly enforced - see GOTO vs structured programming). Thus the simpler topology of the script allows the author a more unfettered medium of expression.
