What

Ten of the buttons hide an easter egg. You find them by playing with the buttons on the docs and landing pages, not with key codes or timers.

Button Do this Egg
SlideToDetonate Slide it all the way (#44) The page explodes and burns down
DemonicButton Hold until the demon is summoned Hell mode for 12s: blood-red site, flickering vignette, pitchfork cursor (Esc ends it). Light mode switches to dark while it's on, without being saved.
DoubtButton Confirm every doubt A terminal rm -rfs every component, then "Everything deleted." and a restore from backup
EvilEyeButton Stare into it (hover 2.5s) Eyes open all around the page and follow your cursor
BrutalButton Smash it 4 times fast The screen cracks around the button, and keeps cracking while you keep smashing
GlitchButton Mash it 4 times fast The whole page glitches: sliced, inverted and RGB-split
RealisticSwitch Flip it 4 times fast The fuse blows and your cursor becomes a flashlight. Two flips whisper "The bulbs flicker…" first.
TrollButton Actually catch it Its revenge: the whole page flips upside down for 6s (Esc flips it back)
ConfettiButton Click it 5 times fast "Party's over": a page-wide storm of 💀 🔥 🖤 confetti
MinecraftButton Mine it until it breaks A creeper swells and hisses "sssss…", then the page blows apart into pixels that sharpen back up

Discoverability

  • Egg counter. A 🥚 pill with a bold found count and a muted total (e.g. 6/10) in the landing nav, the landing footer and the docs sidebar opens an Egg hunt panel. Unfound eggs show a riddle that points at the button, like "The brutal one can take a hit. Can the screen?". Found eggs show how they were done.
  • Chained hints. Every find toast hints at another unfound egg, and clicking it opens the hunt. The detonation end card links there too.
  • Teaser. A first-time visitor gets a one-off "Psst. 10 of these buttons hide easter eggs." toast after 12s.
  • Hunt panel progress is a row of egg pips, filled as you find them, plus "6 of 10 found".
  • Console greeting for curious devs.

How

  • components/easter-eggs/buttons.tsx holds the site's copies of the six buttons. Each one is the registry component, unchanged, plus the interaction that fires its egg. The installable registry files are untouched. The docs MDX and landing previews import these copies.
  • triggers.ts is a small window-event bus (fireEgg / onEgg). The effects live in <EasterEggs /> in the root layout.
  • eggs.ts stores finds in localStorage and keeps the counters live, including across tabs.
  • The styles live in an "Easter eggs" block at the end of globals.css. Reduced motion turns off the flicker, glitch and shake.

Checks

  • pnpm typecheck, pnpm lint (only the existing <img> warnings) and pnpm build pass.
  • Ran every egg in headless Chromium on its docs page by actually using the button. Each effect fired, toasted and cleaned up after itself, and the counter climbed with each find. The old triggers (Konami code, typing boom) no longer do anything. No console errors.

- Konami code (up up down down left right left right B A) toggles hell
  mode: blood-red filter, flickering vignette, pitchfork cursor
- Flipping the theme 6 times in 3s blows the lights: flashlight cursor
- A minute idle and red eyes open in the dark at the edges, watching
- Rage-clicking empty space cracks the screen
- Typing "boom" detonates the page from the middle
- Leaving the tab makes the title beg you to come back
- A console greeting with a hint, and a burn-it slider on the 404

Finds are remembered in localStorage and toasted with an x/7 counter;
the detonation end card shows the count too.

📝 Walkthrough

Walkthrough

The change adds seven tracked Easter eggs and client-side triggers that record discoveries, display notifications, and render visual effects. It adds an egg-hunt dialog and access buttons, extends detonation events with an egg identifier, and mounts the Easter egg components in the root layout.

Changes

Easter egg interactions

Layer / File(s) Summary
Discovery state and feedback
components/easter-eggs/eggs.ts, components/easter-eggs/hunt-store.ts, components/easter-eggs/egg-toast.tsx, components/easter-eggs/egg-hunt.tsx, components/easter-eggs/egg-teaser.tsx, components/easter-eggs/console-greeting.tsx
The egg registry reads and writes discovery progress in local storage. Toasts report discoveries and progress. The dialog lists eggs and supports resetting progress. The teaser can show a toast if no egg has been found.
Discovery triggers and visual effects
components/easter-eggs/use-key-sequence.ts, components/easter-eggs/hell-mode.tsx, components/easter-eggs/lights-out.tsx, components/easter-eggs/screen-cracks.tsx, components/easter-eggs/tab-title.tsx, components/easter-eggs/watching-eyes.tsx, components/easter-eggs/boom-word.tsx, app/globals.css
Keyboard sequences, theme changes, click streaks, tab visibility, and inactivity activate egg interactions. The components record discoveries and render effects. CSS defines the overlays, animations, and reduced-motion rules.
Detonation discovery integration
components/detonation/events.ts, components/detonation/page-detonation.tsx, components/detonation/detonation-overlay.tsx, app/not-found.tsx
Detonation events include an egg identifier, which the page listener passes to egg tracking. The overlay shows discovery progress and can open the hunt after rebuilding. The 404 page includes a detonation control.
Component mounting and hunt access
components/easter-eggs/easter-eggs.tsx, app/layout.tsx, components/docs-sidebar.tsx, components/landing/landing-footer.tsx, components/landing/landing-page.tsx
The root layout renders the Easter egg component collection. The landing page and documentation sidebar provide egg-hunt buttons.

Merge Risk: 🔵 Low · up to 6d5f5

These narrow Easter-egg issues do not block normal site use, but the title can remain changed, a valid Konami sequence can be missed, and discovery counts can disagree when storage is unavailable. They warrant fixes or explicit acceptance before merge.

Keep the original title when the tab is hidden again before the restore timer fires.

After a return, saved is set to null and the title becomes BACK. The original title is kept only in the timer closure. Suppose the user leaves the tab again within 2.2 s. Line 17 clears the timer, and line 18 sets saved to the current title, which is BACK. On the next return, original is BACK, so the restore timer writes BACK again. The tab title then stays "😈 Knew you would." until the next navigation. Quick alt-tab switching is enough to trigger this.

Store the pending original title outside the timer closure and reuse it when you cancel the timer.

Fix the sequence matcher so a repeated key does not break the Konami code.

The fallback resets progress to 1 or 0. That is only correct when no proper prefix of the sequence is also a suffix of the typed keys. The Konami code starts with ArrowUp, ArrowUp. Suppose the user presses ArrowUp three times and then types the rest of the code. On the third ArrowUp, progress drops from 2 to 1. The ArrowDown that follows does not match sequence[1], so the code is never recognized. Pressing up "one extra time" is a common way to type the code.

Keep a rolling buffer of the last sequence.length keys and compare it with sequence.

- Hell mode's forced dark no longer counts as a theme flip

Keep an in-memory snapshot when storage writes fail.

If localStorage.setItem throws, changed() clears the snapshot and the next read returns the old list. The toast can show 1/7 while the hunt dialog shows 0/7, and later finds cannot accumulate. Keep the new list in memory on write failure, then notify subscribers. Persistence can remain unavailable without breaking the current visit.

Each egg now comes from playing with one of the buttons, the way
SlideToDetonate already did:

- DemonicButton: hold until summoned and the site goes to hell for 12s
- DoubtButton: confirm every doubt and a terminal rm -rf's the site,
  then restores it from backup
- EvilEyeButton: stare into it for 2.5s and eyes open around the page,
  following the cursor
- BrutalButton: smash it 4 times fast and the screen cracks around it
- GlitchButton: mash it 4 times fast and the whole page glitches
- RealisticSwitch: flip it 4 times fast and the fuse blows (flashlight)

The Konami code, typing boom, idle eyes, tab title and empty-space rage
clicks are gone. The site uses wrapper copies of these buttons; the
registry components are unchanged. Hunt riddles, teaser and console
text now point at the buttons.
@radiumcoders radiumcoders changed the title More easter eggs around the site Easter eggs hidden inside the buttons Oct 9, 2026
New eggs, ten in all:
- TrollButton: catch it and the page flips upside down for 6s
- ConfettiButton: click it 5 times fast for a page-wide skull storm
- MinecraftButton: break it and a creeper hisses, then the page blows
  apart into pixels that sharpen back up

The count was a thin mono "0/7" that read like a date. It's now a pill
with a bold found number and a muted total (nav, docs sidebar, footer,
toast), a row of egg pips with "6 of 10 found" in the hunt panel, and
"N of M found" on the detonation card.
