What this adds

Builds the next GaugeGap growth layer from the strongest patterns in interactive-science libraries: immediate motion, recognizable presets, one clear challenge, different interaction styles, and shareable run states.

Four playable labs

Butterfly Effect — existing Lorenz attractor tuning, scoring, poster and clip export
Firefly Sync — Kuramoto-style collective synchronization with coupling, noise, population and time controls
Wave Eraser — animated two-source interference field with a movable detector and destructive-interference challenge
Living Chemistry — drawable Gray–Scott reaction-diffusion field with coral, cell, maze and worm presets

Arcade experience

Horizontal/mobile-friendly experiment selector
Surprise-me mechanic
Each lab has distinct interaction: tune, synchronize, explore and draw
Exact URL state sharing for all new experiments
Live challenge scores and mission prompts
Updated homepage copy, lab gallery and audience-growth story
Existing BrainSNN scanner and research workspace remain intact

Code Review

This pull request introduces a new 'Science Arcade' feature (ExperimentArcade) containing four interactive simulations: the Butterfly Effect, Firefly Sync, Wave Eraser, and Living Chemistry. It adds the simulation logic, state management, and styling, while updating the landing page to integrate the new arcade. Key feedback includes addressing a potential TypeError when copying experiments via navigator.clipboard, fixing the Wave Eraser detector intensity to reflect live wave states instead of freezing on pointer stop, ensuring scrollToPlayground does not reference the removed playgroundRef, and adding -webkit-backdrop-filter prefixes in CSS for Safari compatibility.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

+  navigator.clipboard?.writeText(url.toString())
+    .then(() => onNotice('Challenge copied. Send it to someone who thinks they can do better.'))
+    .catch(() => onNotice('Copy was blocked by the browser. Use Share challenge.'));


Using optional chaining navigator.clipboard?.writeText(...) followed by a .then() call will result in a TypeError: Cannot read properties of undefined (reading 'then') if navigator.clipboard is undefined (e.g., in non-secure HTTP contexts or older browsers). Check if navigator.clipboard?.writeText is available before calling it.

Suggested change

navigator.clipboard?.writeText(url.toString())

.then(() => onNotice('Challenge copied. Send it to someone who thinks they can do better.'))

.catch(() => onNotice('Copy was blocked by the browser. Use Share challenge.'));

if (navigator.clipboard?.writeText) {

navigator.clipboard.writeText(url.toString())

.then(() => onNotice('Challenge copied. Send it to someone who thinks they can do better.'))

.catch(() => onNotice('Copy was blocked by the browser. Use Share challenge.'));

+    const value = (Math.sin(k * Math.hypot(px - s1x, py - sy) - timeRef.current)
+      + Math.sin(k * Math.hypot(px - s2x, py - sy) - timeRef.current + active.phase)) * 0.5;


The detector's intensity is calculated using timeRef.current, which continuously changes in the animation loop. However, moveDetector is only triggered on pointer events. When the user stops moving the pointer, the displayed 'Detector energy' score freezes at a random instantaneous value rather than reflecting the live wave state. To fix this without expensive state updates in the render loop, we can calculate the time-independent wave amplitude (envelope) at the detector's position.

Suggested change

const value = (Math.sin(k * Math.hypot(px - s1x, py - sy) - timeRef.current)

+ Math.sin(k * Math.hypot(px - s2x, py - sy) - timeRef.current + active.phase)) * 0.5;

const r1 = Math.hypot(px - s1x, py - sy);

const r2 = Math.hypot(px - s2x, py - sy);

const value = Math.abs(Math.cos((k * (r1 - r2) - active.phase) * 0.5));

+export function GaugeGapLanding({ onStart, onNavigate, onOpenReconstruct }) {


The playgroundRef has been removed from this component, but the scrollToPlayground function (which is called in multiple click handlers) likely still references it. This will cause a runtime error when those handlers are triggered. Please update scrollToPlayground to scroll to the new #playground element directly (e.g., using document.getElementById('playground')?.scrollIntoView(...)).

Recompute Wave Eraser detector energy live

When the Wave Eraser opens or when its sliders/time change, detector.intensity stays at the last pointer event value (0 initially), so the score can report “Near-perfect silence” while the animated field under the crosshair has a different energy. This affects the default startup state and any stationary detector; recompute the detector intensity in the render loop or whenever params/time advance.

+  const visibility = Math.round(Math.abs(detector.intensity) * 100);
+  const state = [params.wavelength, params.spacing, params.phase, params.speed].map((value) => round(value, 3)).join(',');


Include detector position in wave challenge state

When users share a Wave Eraser run after finding a quiet point, the URL only encodes the wave parameters and drops the detector coordinates, while a recipient reloads with the detector reset to the center. The copied/shared link therefore cannot reproduce the node that produced the advertised detector score/title, so include detector.x/detector.y in the state and restore them on load.
