Batik, the art of applying wax to cloth and then tie-dying in colourful and dramatic designs, is produced throughout Indonesia, and the centre of this activity is Yogyakarta in Java. Other craft forms include: ikat, which is a type of weaving with tie-dyed threads; songket, a silk cloth with gold or silver threads woven into it; and kris, artwork often decorated with jewels. Javanese wayang (puppet) plays and gamelan (hypnotic music composed mostly of percussive instruments) are also popular artistic forms.

Many Indonesian dishes are Chinese-influenced, but some, such as Padang food from Sumatra, are distinctly home-grown. Wherever you travel in Indonesia you'll see vendors selling snacks such as potatoes, sweet nuts, biscuits or fruit. Rice is the basis of each meal, eaten as a soup or with an assortment of hot and spicy side dishes, salad and pickles. Nasi goreng (fried rice) is the most common dish, while sate (skewered meats with a spicy peanut sauce), gado-gado (bean sprouts and vegies in peanut sauce) and seafood are also popular. The variety of tropical fruits grown would make a greengrocer swoon. They include custard apples, durians, guavas, jackfruits, mangoes, papayas, starfruits and rambutans.

Social and religious duty has, over time, been refined to form a code of behaviour called adat or traditional law. Islam is the predominant religion of the archipelago but it's somewhat tempered by elements of Hindu-Buddhism, adat and animism. In Java, especially, there are hundreds of places where spiritual energy is thought to be concentrated and can be absorbed by followers. Despite a lengthy colonial period, missionaries were only successful in converting small pockets of the Indonesian population to Christianity - the Bataks of Sumatra, the Toraks of Sulawesi and 95% of the population of Flores being notable examples.
