Question 1

What is Retro CRT Binary Pixel Simulator?

Accepted Answer

This is a zero-dependency web toy that transforms 81 binary digits into a nostalgic CRT terminal display. It's a pure browser simulation with retro visual effects like green phosphor glow, scanlines, and phosphor decay - all achieved through CSS and JavaScript.

Question 2

How does the binary pixel display work?

Accepted Answer

The simulator converts 9×9 binary data (81 total bits) into a visual grid representation. 1s are displayed as bright blocks (█) and 0s as dim blocks (░) in a classic terminal style. The visualization updates in real-time as you type, with optional CRT scanning animation effects.

Question 3

What input formats are supported?

Accepted Answer

The tool accepts multiple input formats for maximum flexibility: 9 digits per line (space-separated), 9 continuous digits per line, or a single line of 81 digits. All formats are automatically detected and converted to the 9×9 grid visualization.

Question 4

Is this a hardware device or native application?

Accepted Answer

No, this is purely a browser-based visual simulation with no hardware components or native app installation required. All CRT effects, including green phosphor glow, scanlines, and phosphor decay, are achieved entirely through CSS and JavaScript.

Question 5

Does it require an internet connection?

Accepted Answer

The simulator is PWA-ready and works offline after the first load. All processing happens locally in your browser - no data is sent to external servers, ensuring complete privacy and offline functionality.

Question 6

Can I save or export my visualization?

Accepted Answer

You can take screenshots of your visualization directly from the browser. The tool also provides built-in examples you can use as starting points for creating your own binary art patterns.
