用 Antigravity Vibe 了个免费无限玩的地理猜图站，全球 Street View 随机降落 大概一个月前迷上了"看街景猜地点"这类地理游戏，但主流的那几个不是要订阅 就是要登录，免费版还有每日次数限制，玩不过瘾。 于是基于一个开源项目搭了个站：World Guesser 。 玩法：Google Street View 随机把你扔到地球某个角落，你根据路牌、植被、 驾驶方向、电线杆、车牌这些细节判断自己在哪，然后在地图上落点，越准分越高。 和主流竞品比，我做了几个刻意的取舍： - 完全免费，无限玩，没有每日次数限制 - 不用注册、不用登录，打开就能玩 - 暂时不挂广告，先把体验做好 - 经典单人模式，多人对战和每日挑战均已上线 技术栈是 Astro + Vue + Cloudflare Pages + Cloudflare Workers ，加载很快，手机浏览器也能流畅玩。 solo 搞的第一个版本，肯定有不少不足，欢迎试玩后直接吐槽，每条评论我都会看。 地址： https://playworldguesser.com

I built an explorable 3D globe of the world economy – click any country, get its economy, or play 18 geography games. 10 weeks, zero runtime API calls globenomics.world — spin a 3D globe, click any country, and get its actual economy: GDP, wages, inflation, its biggest companies, and exactly where it ranks against every other country on 34 metrics. Then there are 18 geography games built on the same data — including one where you name as many countries as you can in three minutes, and one

做了一个在线反应、记忆与专注力测试网站 最近做了一个叫 [PickTests]( https://picktests.com/) 的在线测试站。 反应时间、序列记忆、瞄准训练这些东西，网上其实已经有很多了。真正让我想重新做一遍的，是不少页面要么堆了很多不必要的内容，要么广告和装饰比测试本身更抢注意力，到了手机上也不一定顺手。 所以我给这个项目定了一个比较克制的方向： 不急着增加更多测试，先把每一个已有的测试认真做好。 目前上线了 6 个测试： - 反应时间 - 瞄准训练 - 序列记忆 - 数字记忆 - 多目标追踪 - 斯特鲁普测试 首页：[反应测试]( https://picktests.com/zh/) 网站使用纯 HTML 、CSS 和 JavaScript ，没有账号系统。成绩保存在当前浏览器，打开页面就可以开始。 我现在主要在调整这些细节： - 操作是不是足够顺手 - 测试节奏会不会太快或太慢 - 结果能不能一眼看懂 - 动效和反馈会不会太多 - 手机、平板和电脑上的体验是否一致 目前最想先做好的页面

made a fun little website with AI to explain how the Oceans in FFIX are authored after days of slamming my head against the keyboard trying to deconstruct it

Play Parry — a 2-minute daily puzzle about catching AI's mistakes: spot the planted flaw, catch the answer that's lying to you I have been recently fascinated with puzzles as a way to help improve my BS-radar when using AI. I designed Parry to help with this - One puzzle a day - find the one flaw hidden in a confident paragraph, pick which of two AI answers actually helps you (one is subtly useless), call a claim true/false. Free, no account, nothing you input leaves your devi

Geography/History game: LifeGuessr! Hi all! I worked over the last 3 months on this game: lifeguessr.com The concept is very simple: you get a birthdate, a deathdate (if relevant), and a map, and your goal is to identify the historical figure these details pertain to. Multiple hints are available to make it a bit more fun I have expended it to a wide collection of figures, including contemporary ones. I also had a bit of fun with some custom themes, rewards, etc. This game is comple

Obstruction - A daily sliding puzzle Obstruction is a puzzle where the aim is to slide the green piece to the target. Sounds simple, but pieces have movement restrictions depending on their colour so the solution isn't always as easy as it seems. With a fresh puzzle every day and a short playtime, this game can become a fun habit that slips right into your daily routine.
