The system I selected was the information database, Wikipedia. I started with a simple search term, Signal, and followed what I thought were interesting links from page to page. Many times I have gone down the wormhole that is Wikipedia links, and ended up nowhere close to the topic I started off on.

This particular trip took me from internet history, to U.S governance, back to computer science, to Carnegie and Mellon, to golf, to horse shows, to obsessive compulsive disorders, to polio, to history, to math, to data, to film, to mythology, to national disasters, and finally currency.
