Detailed notes
## Background Published on YouTube by pekkavaa on December 28, 2014, the video features a demonstration of playing level E1M1 of Quake on a Hitachi V-422 oscilloscope. The video description explains that the game is rendered on a laptop and converted into an audio signal, which the oscilloscope then draws as real-time two-dimensional vector graphics.
## TL;DR The demonstration shows classic Quake gameplay rendered entirely as glowing green vector wireframes on a dual-trace Hitachi oscilloscope screen. After an initial reaction of disbelief at the working display, the player fires off several shotgun blasts while navigating the level's corridors. Determined to see how responsive the unconventional setup is, the player decides to push forward and run through the map.
## Atmosphere & style The presentation has the hypnotic, ambient feel of a late-night workbench experiment, juxtaposing crisp, retro shotgun sound effects with the eerie glow of an analog CRT. The mood starts with stunned, quiet awe before pivoting into amused determination as the player actually starts navigating the wireframe corridors. Watching it feels like peeking into a hacker's workshop where vintage test equipment is repurposed into a surreal gaming terminal.

## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=aMli33ornEU&t=0s) Demonstrating Quake on a Hitachi Oscilloscope
The demonstration opens with background music and the distinctive sounds of gameplay as id Software's classic first-person shooter *Quake* (specifically map E1M1) is rendered onto a Hitachi V-422 oscilloscope screen. The visual output is achieved by running the game rendering on a laptop, which converts the scene into an audio signal translated directly into two-dimensional vector graphics on the scope's CRT display. As the player takes in the surreal, glowing green vector wireframe environment, an initial reaction of surprise breaks through with an astonished “Huh?” followed immediately by “Oh, my God.”
Gunfire echoes in rapid succession with three distinct shotgun blasts ringing out across the audio track as the player navigates the vector-drawn corridors and engages enemies. Ready to push forward into the level and test the responsiveness of the setup, the player commits to running the map, announcing, “I'm going to go,” and resolving, “I'm going to try it.”
