As soon as I saw Liners I thought of John Maeda’s work Oneline.com or the One Line Project (images above, left the web based interface, right some of the lines drawn by users); similar ideas but visualised differently. The work is unfortunately not online anymore but I remember contributing to this work around about 2000. According to John Maeda it never quite reached its ambitious goal:

I had proposed a project called the “One Line Project” that would take lines drawn by people and connect all of those lines end-to-end. I was inspired in part by “Hands Across America” and was wondering also if it were possible to realize a line that was as long as the perimeter of the Earth. I wrote a classic server-backended system with a funky JAVA-based client that collected lines from people all oer the world. In 1999 the contents of the line database were reported in an exhibition called “oneline.com,” which was the name of the server…It turns out that after the two years that oneline.com ran, I had only collected around 4 kilometers of line data (using 72 pixels = 1 inch) whereas my goal was 40,000 kilometers.

Below is a video of the interface to the database of user lines.
