✦ Synopsis

In tile present article, we review tile present status of our understanding of the shapes of quasicrystals. Although theoretical efforts exist to determine the equilibrium shape of quasicrystals, very little experimental information exists. We report some preliminary results of our work ill this direction.

On the other hand, beautiful growth shapes of quasicrystals are reported in the literature. However, only recently theoretical attention is paid to the problem of atomistic mechanism of growth. Ill spite of linfited studies, comparison of theory and experiments reveal a difference in growth behaviour between crystal and quasicrystal.
