Any good anagrams for girih?

Girih (Persian: گره‎, "knot", also written gereh) is a decorative Islamic geometric artform used in architecture and handicraft objects, consisting of angled lines that form an interlaced strapwork pattern. Girih decoration is believed to have been inspired by Syrian Roman knotwork patterns from the 2nd century AD. The earliest girih dates from around 1000 AD, and the artform flourished until the 15th century. Girih patterns can be created in a variety of ways, including the traditional compass and straightedge; the construction of a grid of polygons; and the use of a set of girih tiles with lines drawn on them: the lines form the pattern. Patterns may be elaborated by the use of two levels of design, as at the 1453 Darb-e Imam shrine. Square repeating units of known patterns can be copied as templates, and historic pattern books may have been intended for use in this way. The 15th century Topkapı Scroll explicitly shows girih patterns together with the tilings used to create them. A set of tiles consisting of a dart and a kite shape can be used to create aperiodic Penrose tilings, though there is no evidence that such a set was used in medieval times. Girih patterns have been used to decorate varied materials including stone screens, as at Fatehpur Sikri; plasterwork, as at mosques and madrasas such as Hunat Hatun, Kayseri; metal, as at Sultan Hassan mosque, Cairo; and in wood, as at the Great Mosque of Cordoba.
