This particular image, titled "Another Day at the Office," is one of the gems of my personal GIF collection. I believe I downloaded it from CompuServe, and I likely downloaded it on the file date, June 16, 1996.
The image itself is a computer-crafted ode to Doom II that merges a real digitized photograph with imagery ripped straight from id Software's famous first-person shooter.
Such a passion for Doom II in the workplace isn't foreign to me. In an office where I worked in the mid-late 1990s, certain engineers were known to play late night four-player Doom deathmatches over the company LAN.
