The plastic arts are also widespread throughout the island. In addition to the tradition of silk weaving and lamba production, the weaving of raffia and other local plant materials has been used to create a wide array of practical items such as floor mats, baskets, purses and hats. Wood carving is a highly developed art form, with distinct regional styles evident in the decoration of balcony railings and other architectural elements. Sculptors create a variety of furniture and household goods, ''aloalo'' funerary posts, and wooden sculptures, many of which are produced for the tourist market. The decorative and functional woodworking traditions of the Zafimaniry people of the central highlands was inscribed on UNESCO's list of Intangible Cultural Heritage in 2008.
