## Artifact

**Image file:** `mostly_harmless_towel_included.png`  
**HTML page:** `index.html`  
**Theme:** International Towel Day, Douglas Adams / *The Hitchhiker’s Guide to the Galaxy* inspired, humorous Wimmelbild-style world map.

## Original user prompt

```text
Please create a world map to celebrate Douglas Adams Hitchhiker's Guide to the Galaxy. It should be about International Towel Day and all the things a towel can be use to do. Please make the map a static image and funny... a kind of Wimmelwelt style pastiche of towls being used to a ton of different things around the world. Feel free to include some aliens and spaceship art too to tie it into the Hitchhiker's theme (e.g., dolphins flying to space or something? LOL). Whatever comes to mind from the books. Perhaps give the map a witty name like "Mostly Harmless: Towel not Included" or something similar that makes even more sense. 

Thanks!

## Expanded image-generation prompt used

```text
Create a static illustrated world map poster celebrating International Towel Day with a humorous science-fiction literary homage vibe. Make it an original, funny, richly detailed Wimmelbild-style picture map with many tiny scenes and discoveries. Image A is a style reference for the cute, expressive cartoon-towel feeling; use it only as loose inspiration for some towel personalities, not as something to copy.

Show a readable world map with stylized continents and oceans, but turn the whole thing into a dense visual pastiche of towels being used in absurd and clever ways all around the globe. Include dozens of mini-scenes across different regions: towels used as beach towels, picnic blankets, superhero capes, scarves, turbans, hammocks, slings, sunshades, tablecloths, napkins, bandages, parachutes, makeshift sails, pillows, yoga mats, flags, robes, and emergency spaceship-repair rags. Add a few towel characters with funny faces, but also many ordinary towels in use.

Tie it into the Hitchhiker’s Guide to the Galaxy spirit without copying official art: include whimsical aliens, cheerful robots, improbable spaceships, a few dolphins flying joyfully into space, a towel-wrapped interstellar hitchhiker, and small absurd sci-fi incidents scattered around the map. The humor should feel clever, dry, and playful.

Use a colorful, polished illustrated style with lots of tiny details, cartoon energy, and a whimsical world-atlas feel. The composition should be busy but organized, with oceans, landmasses, small decorative icons, and many discoverable jokes. Add a prominent title at the top in a fun hand-lettered/cartoon display style: "Mostly Harmless: Towel Included". Add a smaller subtitle beneath it: "An International Towel Day Atlas of Improbable Uses".

Make the overall look charming, funny, and suitable as a high-quality poster-like static image. Keep it lighthearted, map-forward, and full of visual gags.

## Production rationale

I interpreted the request as a single poster-like static map rather than a navigable web map. The composition emphasizes a dense Wimmelbild/picture-map layout, because that allows many small towel-use jokes to coexist without needing popups or interactivity. I kept the literary references indirect and playful—towels, cheerful interstellar hitchhikers, dolphins, improbable spacecraft, aliens, robots, and dry guidebook-style labels—rather than copying official Hitchhiker’s Guide artwork. The title was adjusted to “Mostly Harmless: Towel Included” because it felt punchier and slightly more optimistic while still nodding to the requested phrase.

## Layout and website notes

The HTML page is intentionally minimalist and has no visible title. The image is centered in the browser window and uses orientation-aware CSS:

- In landscape orientation, the image fills the viewport vertically with `height: 100vh` and `width: auto`.
- In portrait orientation, the image fills the viewport horizontally with `width: 100vw` and `height: auto`.
- Overflow is hidden so the poster behaves like a full-window static display.

A small, unobtrusive provenance download link appears in the lower-right corner.
