A stupa is a moundlike architectural structure closely related to Buddhism. Some stupas contain Buddhist relics. The large Borobudur Temple, in Jogjakarta, Indonesia, has a complex of 73 main stupas. In this Demonstration you can vary an algorithmic stupa based on the stupas in Borobudur.
Borobudur Temple (760 AD), a world heritage site in Java, Indonesia, is a big stupa with thousands of small-sized stupas inside. This has become the cause of the self-similarity obviously found at the temple. It is a wonder how such a complex megastructure was built when there was no universal metric system known in ancient Javanese culture. The hypothesis that the workers used the ratio head:body:foot = 9:6:4 among parts of the temple was proposed by Atmadi (1988). Thus the ratio explains some aspects related to the three-dimensional form of the Borobudur Temple, as well as the other small stupas there.
