Highlights

Ultimate Fluid Sim

Ultimate Fluid Sim is a fluid simulation that makes use of the Smoothed Particle Hydrodynamics method. Built from scratch, it is capable of simulating multiple liquids with different viscosities and densities, gasses, and interactions with solids. It features many optimizations to speed up the simulation, such as positional hashing. It uses the Runge-Kutta 4th order integration method, rather than the Explicit Euler method, which allows for much greater simulation accuracy.

Ant Colonies

An implementation of Kenneth Stanley's NeuroEvolution of Augmenting Topologies (NEAT). In this implementation, ant colonies compete against each other for food. The best colonies produce similar colonies, making the colonies progressively better. It is able to simulate fighting, food, pheromones, offspring, and nest raids.

motus.

A wheelchair controlled with your eyes, submitted to Hack the North 2023. All circuitry, code, and construction was built in the span of 34 hours, from an office chair and provided eye-tracking glasses.

Mr. V Simulator

Mr. V Simulator is a first person stamper game (because g*ns are not school appropriate). It uses a 3D engine built from scratch, which uses raycasting. Navigate through a maze, and make it to the next level, while stamping assignments with Mr. V's stamp of approval. Make sure not to let the assignments get too close! The maze generation algorithm is entirely original. Your score increases with every assignment stamped, based on your current level.

Realistic Obama is a 1:1 replica of Barack Obama, the 44th President of the United States (99.4% accuracy). He was built by Moulik Budhiraja, Jeffrey Zang, Li Feng Yin, and Daniel Zhang in just 34 hours for Hack the North 2025. fun fact: our Devpost page is the 4th-most liked Hack the North project ever!
