Fluoddity: Evolving Digital Lava Lamps

Watch thousands of tiny particles wander across your screen, leaving behind glowing trails that act like a digital nervous system. Fluoddity lets you play god with these blobs by tweaking sliders that change how they sense their environment. The real magic happens because each particle has its own tiny, randomized brain made of math rules. When you click on a particle you love, you can clone it, mutate its brain slightly, and watch the new generation evolve into something completely different. It feels like watching an interactive lava lamp that actually thinks, creating swirling rivers, branching lightning, or strange microscopic life forms as you guide their evolution.

Polymarket 5-Min Arbitrage Bot

This Rust-based bot automatically hunts for pricing errors in Polymarket’s five-minute crypto prediction markets. It monitors the combined cost of buying both "yes" and "no" tokens and triggers a trade whenever that total dips below one dollar. Once both tokens are purchased, the code automatically merges them back into stablecoins, capturing a small but consistent profit from the pricing gap. It also handles risk management by balancing positions and cleaning up trades right before the timer runs out, offering a complete automated loop for short-term market inefficiencies.

Project Caribou Drone Design

Project Caribou is the hexacopter project that finally treats every motor arm as its own independent power station. Instead of wiring one giant battery to six motors like a traditional drone, this design gives each of the six arms its own dedicated smart battery pack and custom safety board. The clever part is the hardware kill switch: a physical cutoff that cuts power at the battery stage before it even touches the electronics, ensuring the flight computer can never accidentally cause a short circuit. This repository collects all the engineering blueprints, custom circuit board files, and 3D models that make this safe, scalable drone architecture possible.
