Many Iranians sculptors are still experimenting with the expansion of the forms into space, paving the way for further serious artistic achievements. Many others search for traditional motifs, or for familiar patterns of Persian calligraphy, architecture or design, linking to the past artistic heritage. Some others have surpassed the formal concerns, expressing socio-political statements or displaying levels of self-disclosure, especially by incorporating their typically used everyday objects. A number of the sculptors have used text and language as a means of artistic expression, and yet others have gone further into interpretable combinations of text and objects.
