Yes, but can it run DOOM?
Here is a video of a doom-alike in excel, explained by someone with a bird on his head. He's not clippy, but a real person with a bird on his head. [1]
Here is a video displaying a walk-through of the Excel easter egg that showed the Hall of Tortured Souls! [2]
There was a Windows 95 screen saver that was Doom like though.
95 had the “Hall of Tortured Souls”—a 2.5D first-person walker—which was more Doomlike.
