GopherVR is an enhanced Internet Gopher client that includes a 3D visualization tool for viewing resource collections as 3D scenes. The 3D view was intended to be similar to 3D games of the time, like Spectre.
In 1995, the Gopher developers at the University of Minnesota released GopherVR. Using Gopher+ protocol extensions, spatial positions for Gopher resources are specified, and GopherVR clients combine traditional gopher hierarchy browsing with 3D scene navigation. It was primarily written by Mark P. McCahill, Paul Lindner and Neophytos Iacovou. This original version was available for Unix, using Motif and X11, and the classic Mac OS; although incomplete, they were offered as partially functional alpha versions for testing.
The software packages for GopherVR were stored on the UMN Boombox FTP server and (probably due to a defective backup and restore) virtually all Gopher software on this server over 96k in length had become corrupted, resulting in the loss of all publicly available copies of the source code until it was rediscovered and made available by Mark McCahill in June 2008.
In December 2009, GopherVR was re-released by Cameron Kaiser in an updated form for Mac OS X, Linux and other platforms. It is still considered incomplete.
