# CRT Power On / Off: motion graphics style

> A cathode-ray tube switching on: a bright dot stretches into a line, snaps open into a curved, glowing picture with scanlines, then collapses back to a dot. A nostalgic transition for intros, outros, retro reveals and channel-style edits.

## Prompt (replace [TEXT] with your text)

```text
Show [TEXT] on an old cathode-ray tube TV that switches on and off. The screen starts dark gray glass with a soft reflection. A tiny white-hot dot appears in the center, stretches into a thin horizontal line, then the picture opens vertically, overbright and slightly blurry, and settles over a second. The picture: [TEXT] in a heavy geometric sans with a hot pink to amber to cyan gradient, glowing over a deep teal-black field. Bulge the glass with barrel curvature, darken the corners, add fine scanlines, an RGB stripe mask, phosphor bloom and a faint slow hum bar. Frame it in a rounded charcoal bezel. After a few seconds collapse the picture into a bright line, then a dot that fades with afterglow; loop every 8 seconds.
```

## Visual DNA

- Power-on beam: center dot, horizontal line, then the picture opens vertically
- Curved bulging glass with darkened corners inside a charcoal bezel
- Visible scanlines and an RGB phosphor stripe mask up close
- Bloom and overexposure that settle as the tube warms up
- Power-off collapse to a line and a dot that fades with afterglow
