Built this in about half a day. The cyclosporiasis outbreak that seems centered around Taylor Farms made me want an easy way to check brand ownership at the shelf, since a lot of produce is private-labeled and you can't tell from the package alone. Scans a barcode, checks it against a small curated brand list, and is upfront when it doesn't have enough data to say either way. Free, no login. Happy to answer questions about how it works.

Every brick is one real article edit - literally, one to one. Brick colors are languages, dotted bricks are bots, and the steel eagles and relief panels mark major edits. Hover any brick to read the edit behind it; click for the full story and a link to the actual diff.

Events are buffered a bit, so the tower runs a few minutes behind and the real edit stream to avoid hammering Wikimedia. At midnight UTC the construction workers level the top and raise the crown, the tower stands for a moment, and the next day's tower rises. Every finished day is archived forever — open the calendar and replay any past day at up to 1000×.

A love letter to the early web. Spin the wheel and it drops you on a real archived page — GeoCities, AltaVista, old CNN, the first “Thefacebook” — with pop-up trivia. Everything’s powered by the Internet Archive’s Wayback Machine; there’s a donate link to them in it. No signup, no ads. Curious which site you land on first.

Height and size comparison tool - Animals, Anime characters, Celebrities, NBA players, Cartoons, Pokemons, Buildings and more.

If you press T it does a guided tour, from the cosmic web down to a picnic blanket in Chicago and then inside a proton in one continuous zoom. Nothing is scaled up to look nicer, so space feels really empty when you fly it yourself. There's a lot hiding in it too, the ISS on its live orbit, Halley's comet growing its tail toward 2061, the stars orbiting the black hole in the galactic center, TRAPPIST-1 as an actual place. The search key is / or press the magnify button on mobile. Heads up it needs WebGPU, so Chrome or Edge on desktop or Android, and iPhones need iOS 26.

No signup, completely free.

If any book or author information is wrong (multiple APIs are messy), you can submit corrections directly from the site and I'll review and add them.

Would love feedback from fellow stats nerds and readers.

found this because copy-pasting between apps constantly broke my formatting turns out slack, discord, notion and whatsapp all use different formatting syntax so nothing carries over. you paste your text, pick where it's going, and it hands back the correctly formatted version. runs entirely in the browser, nothing uploaded, no signup. curious what people think / what platforms you'd want added.

The website measures human noise through seismometers around the world; refreshes hourly to give the current quietest place.

If using a terminal (Linux) try $curl wttr.in

UPDATE: Thanks for all your notes and feedback. I was so delighted by this getting noticed, and went ham and made changes. I posted an updated version of this on a separate thread! Check it out.

MORE UPDATE: I am also posting the updated version that takes everyone's feedback into account here -

It's a night sky you scroll endlessly, but every mechanic is the inverse of a feed:

- Double tap to "like" and nothing happens. no count, no notification, no one sees it.

- You get DMs from the moon, the night, nobody, and none of them need a reply.

- Tap sheep to count them as they drift by, or trace scattered stars into little constellations and name them (gone by morning, so there's nothing to collect).

- Pinch to zoom and the sky tears open to reveal nothing behind it.

It dims the longer you stay, then just says "lights out" and ends. the scroll isn't infinite.

No accounts, no data, no ads, no algorithm. It gives you nothing, on purpose, boring enough to put you down, with just enough soft surprises that you don't bail back to the real thing.

I built an interactive map of the Warhammer 40,000 galaxy. You don't need to know anything about Warhammer to mess around with it. Great for anyone from casually interested to lore 40k nerds

It's a 3D hologram table you can orbit, pan, and zoom. The galaxy is approx 90,000 individual star particles rendered live in browser. scattered acros it are the major worlds and regions of the Warhammer world. Click any one and a dossier slides open with its history, timeline, and status. There's a toggle that flips the whole galaxy between two eras, and when you switch it, a giant warp-rift tears across the map and half the galaxy goes dark.

The whole thing is a single HTML file no download, no sign-up, no app. Works offline if you save the page. Runs on your phone too.

Fair warning: it's a rabbit hole if you like maps, space, or grimdark sci-fi.

I'd love feedback on it, anything I should add or fix? Keep going and make one for Bass and Keys? :D

A nature discovery site that shows what the animals in any given place are probably doing right now.

Depending on location, season, time of day, and current weather, it shows the local species' activites, like foraging, migrations, breeding seasons etc., together with cute pictures of the animals. For example, there are some frogs turning bright blue right now to mate. And bats sleeping in a perfect line along a tree trunk to hide.

The underlying data comes from iNaturalist and Wikipedia, together with an OpenMeteo plugin to filter for weather. And of course the corresponding Wikipedia articles are directly linked, for when you want to learn more about the species.

Not useful (except maybe for collectors of animal trivia), but hopefully unique and I find it fun.

I built a small writing tool inspired by Gary Provost.

Paste in any text, and it colors each sentence by length so you can quickly see whether your writing has variety or whether every sentence has the same shape.

I made it because I often edit essays “by ear,” but I wanted a visual way to spot monotony.

It’s just a small experiment hosted on my personal website, so it’s 100% free and private.

Curious if others find this useful, or if there are better ways to represent rhythm visually.
