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

```text
Make an extreme close-up of a soap film where [TEXT] appears through thin-film interference. Against black, the film fills the frame with slowly swirling, marbled rainbow colors: vivid magentas, golds, teals and blues near the top where the film is thinnest, softer pink-and-green pastel bands toward the bottom, with gentle eddies and a faint soft reflection of a window. In the middle, [TEXT] in a heavy grotesque sans gradually drains into ultra-thin film that looks pure black, each letter outlined by bright silver, gold, magenta and blue fringes, and the letters wobble slightly with the flow. Hold, let the film refill and wash the word away, then loop. Slow, hypnotic, physically believable.
```

## Visual DNA

- Swirling interference colors computed from real film thickness
- Word drains to black film, ringed by the classic first-order fringes
- Gravity layering: thinner, brighter colors at the top, pastel bands below
- Slow eddies and marbling with a faint window reflection
- Deep black surround that makes the colors glow
