• large scrolling text, fullscreen (tap to exit)
• seamless looping marquee (no gap between repeats)
• configurable scroll speed
• configurable text and background colors
• configurable font
• keeps the screen awake while scrolling
• locks to landscape on mobile
• shareable links — the message is stored in the URL hash
• dark mode support
• respects reduced-motion preferences
• single-page webapp, no dependencies

1. Open the app.
2. Type your message and tweak the font, colors, and speed.
