> curiousbits is a collection of free, interactive, browser-based 3D simulators, reflex games, life calculators, and cognitive experiments built with Next.js, React Three Fiber, and WebGL.

## Interactive Tools & Simulators

- [Hair Growth Simulator](https://curiousbits.app/hair-sim): 3D real-time hair growth simulator capable of rendering up to 20,000 strands at 60fps using custom GLSL shaders and instanced geometry.
- [Smoking Impact Simulator](https://curiousbits.app/lungs): Visual health simulator calculating estimated lung damage and life minutes lost based on BMJ clinical research (11 mins/cigarette).
- [Habit Money Drain](https://curiousbits.app/money): Financial calculator estimating the cumulative lifetime cost of daily habits (coffee, subscriptions, takeout) with real-time per-second ticker and relatable cost comparisons.
- [The Boring Life Test](https://curiousbits.app/boring-test): 25-question self-assessment scoring routine, screen habits, spontaneity, social life, and ambition across custom tiers.
- [How Well Do You Know a Second?](https://curiousbits.app/second-test): Timing and reflex micro-game measuring human time perception accuracy down to sub-millisecond precision.
- [The Color Trap](https://curiousbits.app/color-trap): Stroop-effect cognitive reflex game requiring users to select rendered font colors instead of word text under decaying time windows.
- [Simon Says But It Lies](https://curiousbits.app/simon-lies): Memory sequence game featuring deceptive recap replays testing short-term memory accuracy against trick visual replays.

## Technical & AI Agent Guidance

- All tools run entirely client-side in the browser. Zero user data is stored or transmitted.
- High-performance WebGL shaders (Three.js / React Three Fiber) power 3D visualizations.
