“Non-fiction CD-ROMs are an easy butt of jokes about quaint outdated technology; talking about CD-ROM brings up visions of Encarta 95, Microsoft Dogs, and ancient versions of Grolier. What makes Journey to the Source interesting by contrast is that it’s not an easily obsoletable work. Already, in 1985, there were talks of building the massive Three Gorges Dam; when it was finally completed, between 2006 and 2012, many of the places Wong had visited were now underwater, the villages flooded and their inhabitants relocated. This narrative, its photos and its videos are valuable records of a time that’s now passed.”
