Gopher was a menu-driven, mostly text-based protocol designed to serve documents and other resources in the early 1990s, before the World Wide Web became dominant.

Initially, gopher clients were designed for text-based terminals, but early graphical web browsers supported the protocol as well, however this functionality was later removed.

Use a gopher client or plugin to explore gopherspace at: gopher://blizzardofzeros.com

For more information on how to do this, try apt-get gopher or similar on your Linux system, or download the Overbite browser plugin at Floodgap.

There are several Winsock clients available for Windows 3.1x, and early browswers may support gopher links natively.
