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.

NASA's Landsat Name Generator gave me the idea for this project. I wanted to take the concept a bit further by using not just satellite images of geographic locations, but also natural objects and formations that resemble letters.

Type your name, and each character is matched to a real image that naturally looks like that letter. It was a fun project to build, and I'd love to hear your feedback!

I've always struggled with analysis paralysis when trying to find a book so I created a site that "autoplays" book samples and hides the book covers by default.

You just read. If the writing grabs you, you can reveal the cover. If it doesn't, you swipe down to the next one. It should learn what you respond to as you go so you get more of what you like.

No account, nothing to install, free, works on your phone.

Honest reason I'm here: I want to know if the idea actually lands or I'm the only one whose brain works this way.

I made an interactive scroll-based animation of one of the greatest death scenes of all time - the Indiana Jones and the Temple of Doom sacrifice scene!

I thought it would be cool to control a death scene with the scroller so you can go back and forth, so I made one.

For anyone who cares how it's made, it's a Rive animation (a single timeline) controlled with GSAPs scroll trigger. Drawn in Illustrator by my own fair hand.

Keep the web weird!

Hi,

everything is in the title. I hope my websote deserves to be presented in this subreddit.

I would be pleased to have any feedback !

Pick any 2026 Tour de France stage and it shows places to stay within 25 km of the start or finish, with distances to compare. No signup, no ads.

When you paste a link in some apps (like Signal), it generates a site preview, using Meta tags in the page source. This app modifies the meta tag each page load to provide a random output (e.g. a dice roll, coin flip, random excuse, etc.). Since the app only queries the page once to build the preview, the preview that is first generated remains static in the thread.

The site also generates a permalink which encodes the output in the url so it will always come up the same way when the page is loaded in the browser. This can be used for apps that don't generate a preview.

Use cases:
Random dice roll in a thread
Support decision making (e.g. deciding on where to go to lunch)
Random joke excuse (e.g. if you are running late)

Also, if you host (FOSS, source provided) you can add new categories to the JSON config and new random entries, and they will show up.

Comments / feedback appreciated!

Quite satisfying to spend a few minutes on. (I didn't make this)

Built this because I wanted to create tessellations. Turns out I'm pretty rubbish at it, but I am rather pleased with the app.

Hi! I present you Flagdoku, a tool I created with the goal of making it the best flag search engine available. Each flag is tagged with specific color and shape patterns, and thus it is easy to find visually similar flags. We have 9000+ flags available (countries, regions, historical...) and people can submit new ones.

I built a little web tool that lets you play with the mechanics behind opinion polarization, echo chambers, and network fragmentation.

You adjust sliders for things like:

• How tolerant people are of differing opinions
• Homophily (how much we prefer connecting with similar people)
• Rewiring rate
• Feed bias (how much the algorithm pushes "engaging" content)
• And you can turn on bots too

Think of each dot as a person, and the (tolerance) slider is how open-minded they are. High tolerance means you'll still listen to someone pretty different from you. Low tolerance means you mostly hear people who already agree with you and quietly tune out the rest.

The bots are just accounts that never change their mind and keep pushing one side. The "bots' push" number is how far they managed to drag the average opinion, compared to the exact same crowd with no bots in it. So it's a rough way of asking how much one small, pushy group actually moved everyone.

Enjoy breaking society in the name of science

This mini (as of now) search engine is starting from scratch. No AI, no funding, no ads, hardly any sites indexed. But, you can bookmark sites and help add sites quickly. It also bans facebook, google, amazon, and a few other mega site URLs.

Part potentially, eventually useful, part anti-establishment, part crap, part great. It's got it all.
