SHRINK变小探险

Every picture here is a real microscope slide, scanned so sharp you can shrink until you see single cells. Pinch, scroll or press + to shrink.这里的每一张图都是真正的显微镜玻片，扫描得非常清楚，你可以一直缩小，直到看清一个一个的细胞。双指捏合、滚动鼠标，或者按 + 变小。

A postcard shows a real spot. Find it: right place, right size. The bars light up as you get close.明信片上是一个真实的地方。找到它：地方要对，大小也要对。越接近，信号格亮得越多。

Make a postcard做一张明信片

Can your friend find your spot?你的朋友能找到你的地方吗？

Put the spot in the middle of the screen, at the size you want them to find it.把那个地方放在屏幕正中，缩到你想让朋友找的大小。

What SHRINK is, and what it is not变小探险是什么，不是什么

SHRINK is a free zoom game for curious children (about 7 to 12, and anyone older) built from 32 real microscope slides: the kind of prepared teaching slides schools use, scanned at 20× so that one pixel is 0.5037 µm across. Nothing in the pictures is drawn or generated. The 25 postcards in 6 expeditions were placed one by one on real structures by the AI that wrote the game. Every slide's size and the screen's width are computed from pixels; the sizes in the postcard facts were estimated on the slide and rounded.

变小探险是一个给好奇孩子（大约 7 到 12 岁，大一点的也欢迎）的免费缩放游戏，用的是 32 张真正的显微镜玻片：就是学校里用的那种教学切片，用 20 倍扫描，每个像素只有 0.5037 µm。图里没有任何东西是画出来或生成出来的。6 个探险里的 25 张明信片，都是写这个游戏的 AI 逐个放在真实结构上的。每张玻片的大小和屏幕的宽度都由像素算出；明信片知识里的尺寸是在玻片上估量后取整的。

How it plays怎么玩

  • All the slides lie on one table at their true size. Zooming in is shrinking: the top bar says how wide the screen is and compares it with hairs, dust mites or red blood cells when one of them fits.
  • A postcard shows a real spot. It only counts when the child reaches the right place and the right size, so the game teaches the habit microscopists use: scan at low power, then zoom in to confirm.
  • Before the answer, children name what they found in their own words. The field guide keeps both names: theirs and the scientists'.
  • They can make postcards for each other: frame a spot, press the envelope, send the link. Good for a class treasure hunt.
  • No timers, no scores against anyone, no streaks.
  • 所有玻片都按真实大小摆在同一张桌子上。放大就是变小：顶栏会告诉你屏幕现在有多宽，合适的时候拿头发、尘螨或红细胞来比。
  • 明信片上是一个真实的地方。只有孩子既找到对的位置、又缩到对的大小才算数，这就是显微镜工作者的习惯：先用低倍找，再放大确认。
  • 看答案之前，孩子先用自己的话给找到的东西起名字。探险手册会把两个名字都记下来：他们的，和科学家的。
  • 孩子们可以互相出题：把一个地方框好，点信封，发出链接。很适合全班的寻宝游戏。
  • 没有计时，没有排名，没有连续打卡。

Privacy and safety隐私和安全

  • No accounts, no ads, no tracking, no cookies. Progress is saved only in this browser (local storage, from the first visit) and never sent anywhere. "Start over" in the field guide empties it; clearing the site's data removes it.
  • Everything the game loads, the slide pixels included, comes from x-wow.com itself: no other server is contacted.
  • "Read it to me" uses only a voice that runs on this device; if there is none for the language, the button says so and stays silent.
  • Challenge links carry only a slide, a position and a size: nothing a child types ever goes into one.
  • The slides are animal, plant and fungus specimens. Slides of human tissue and of disease (14) and of mammalian reproductive organs (6) from the same box were left out. On 11 October 2026, 8 more organ slides (heart muscle, stomach, kidney, liver, small intestine, lung, spleen and spinal cord) were taken out too: their labels don't say which animal they came from, and the same box held human slides.
  • Two specimens are poisonous plants (castor beans, oleander); their slides say so.
  • 不用注册，没有广告，不追踪，不用 cookie。进度只保存在这个浏览器里（本地存储，第一次打开就会写入），不会发送到任何地方。探险手册里的“全部重来”会把它清空；清除这个网站的数据就会把它删掉。
  • 游戏加载的一切，包括玻片的像素，都来自 x-wow.com 本身：不联系任何别的服务器。
  • “读给我听”只用这台设备上本地运行的语音；如果没有这种语言的本地语音，按钮会说明并保持安静。
  • 出题链接里只有一张玻片、一个位置和一个大小：孩子打的字从来不会放进链接。
  • 这些玻片是动物、植物和真菌标本。同一盒里的人体组织和疾病玻片（14 张）、哺乳动物生殖器官玻片（6 张）都没有放进来。2026 年 10 月 11 日，又撤下了 8 张器官玻片（心肌、胃、肾、肝、小肠、肺、脾和脊髓）：它们的标签没有写是哪种动物的，而同一盒里有人体玻片。
  • 有两种标本是有毒植物（蓖麻籽、夹竹桃），对应的玻片上写明了。

Where the slides come from玻片从哪里来

A box of 91 commercial teaching slides, scanned on an Aperio slide scanner. The web copies (276 MB) were white-balanced so empty glass reads white, cut into 512-pixel WebP tiles and packed into one PMTiles file per slide. The original scans of the 32 slides used (0.82 GB) are kept with the slide-label photos and the scanner's ID fields removed and every image tile byte-identical; the owner scanned them, not as part of any job, and chose CC0 1.0 for them on 11 October 2026; they wait in an unpublished Zenodo draft until the owner publishes it. One printed label in the box was wrong (a lily anther labelled as a rotifer); the game names what the tissue shows.

一盒 91 张商业教学玻片，用 Aperio 切片扫描仪扫描。网页版（276 MB）做了白平衡，让空玻璃显示成白色，再切成 512 像素的 WebP 小块，每张玻片打包成一个 PMTiles 文件。用到的 32 张玻片的原始扫描（0.82 GB）已经保存好，去掉了玻片标签照片和扫描仪的身份字段，每一块图像数据都和原来逐字节相同；扫描是网站主人自己做的，不属于任何工作，主人在 2026 年 10 月 11 日决定用 CC0 1.0；它们放在 Zenodo 一份还没发布的草稿里，由主人来发布。盒子里有一张标签印错了（百合花药被标成了轮虫），游戏里按组织实际是什么来命名。

Checking the facts核对事实

Each postcard's fact is one or two plain sentences, written to be true and checkable; sizes come from the pixels. The facts and the game were written by an AI (Claude by Anthropic, used through Claude Code), working from the X-WOW owner's brief and orders. If you spot a mistake, a grown-up can email info@x-wow.com and it gets fixed.

每张明信片上的知识只有一两句大白话，力求准确、可以核查；尺寸都由像素算出。这些知识和游戏是 AI（Anthropic 的 Claude，通过 Claude Code）按 X-WOW 主人的要求和指令写的。发现错误，请大人写信到 info@x-wow.com，我们会改。

The game's code and text, and the slide images: CC0 1.0 (the images since 11 October 2026, the owner's decision). Built with OpenSeadragon (BSD-3-Clause), PMTiles (BSD-3-Clause) and fflate (MIT, inside PMTiles); their licences ship with the site.

游戏的代码和文字，以及玻片图像：CC0 1.0（图像自 2026 年 10 月 11 日起，由网站主人决定）。用到了 OpenSeadragon（BSD-3-Clause）、PMTiles（BSD-3-Clause）和 fflate（MIT，包含在 PMTiles 里），它们的许可证随网站一起发布。
