Internet Archives featured a discussion with Ted Nelson, who describes how ZigZag works. The goal of the Internet Archives team was to see what could be done in one month to move the ZigZag project forward.
A demo of how to use ZigZag with the Internet Archives' Open Library is shown about 12 minutes into the 28 minute video.
Below is a 2008, more polished video with Ted Nelson on introducing ZigZag data structure. Ted has worked on the project for 20 years.
