Islamic designs originate from the old Islamic world and can be found throughout the Muslim world today. Arabic calligraphic designs take many forms and can include strictly geometric patterns or a mixture of calligraphy and geometry seen in Zelij tiles from Morocco. Different Islamic regions also favor certain design elements, with Egypt commonly using natural forms and Turkey preferring floral motifs. Complex geometric patterns are created through interlocking shapes, though sometimes simple ideas can result in complex designs and vice versa.
