  We introduce a simple geometric model which describes the kinetics of
fragmentation of d-dimensional objects. In one dimension our model coincides
with the random scission model and show a simple scaling behavior in the
long-time limit. For d>1, the volume of the fragments is characterized by a
single scale 1/t, while other geometric properties such as the length are
characterized by an infinite number of length scales and thus exhibit
multiscaling.
