Frequently asked questions
How do I download the Aurora ASCII background?
Use the toolbar at the bottom of the fullscreen view. PNG snapshot exports the current frame as a styled image (background, color, glow). Animated HTML exports a self-contained .html file that replays the animation in any browser. TXT exports just the current ASCII frame, and Copy ASCII puts it into your clipboard.
Can I embed the Aurora background on my own site?
Yes. Click "Copy embed" in the toolbar to get an <iframe> snippet pointing at asciify.art. Width, color, speed and font size are encoded in the URL, so it stays exactly the way you configured it.
Is the Aurora background a video or images?
Neither. It is pure JavaScript: every frame is procedurally generated character-by-character at the size of your viewport. No image assets are downloaded, and no video file is streamed.
Can I customize color and speed?
Yes. Pick one of the preset colors, use the native color picker for any RGB value, adjust speed from 0.1× to 3×, and change font size from 6px to 24px. The PNG / HTML / embed export uses the current settings.
Does it work offline?
Yes. After the first load the page caches its assets and works without a network connection. The downloaded animated HTML file is self-contained and runs offline too.
