Sanxingdui (Chinese: 三星堆; pinyin: Sānxīngduī; literally "three stars mound") is the name of an archaeological site in China, now believed to be the site of an ancient Chinese city. The previously unknown Bronze Age culture was re-discovered in 1987 when archaeologists excavated remarkable artifacts, that radiocarbon dating dated as being from the 12th-11th centuries BCE. Leaving behind nothing in the historical record, not even in myth, the unknown culture that produced these artifacts is now known as the Sanxingdui Culture. A museum housing the artifacts is located near the city of Guanghan.
That in mind, the most this project aims for is a collaborative representation of these graphics in an online format. 3d models would be great, but aren't totally necessary at this point. Pen-and-ink illustrations are preferred to photographs at this stage. Vector drawings made in Inkscape, because they can be imported and exported, are probably the middle-ground between a 3d model and a pen-and-ink drawing.
The project shouldn't require much commitment. With a few hours a month from each contributor, we could have something really nice eventually.
