Phun Algodoo |best| Jun 2026

Initially released as , the software was a groundbreaking, free-to-use 2D physics sandbox. Ernerfeldt created it to allow users to draw, move, and interact with objects in real-time, governed by realistic physics constraints. Key Features of Phun:

Whether you want to build a virtual grandfather clock, test an aerodynamic car design, or just watch thousands of water particles flood a digital town, Phun and Algodoo offer an timeless, unmatched platform for creative experimentation. phun algodoo

Behind Algodoo's playful exterior lies sophisticated technology. The physics engine uses by Claude Lacoursière, enabling stable and accurate rigid body simulations. The fluid simulation employs Smoothed-Particle Hydrodynamics (SPH) , creating realistic water, gas, and other fluid behaviors. Initially released as , the software was a

: Phun quickly went viral on YouTube, where users shared complex Rube Goldberg machines, vehicle designs, and mechanical simulations.

The software began as Ernerfeldt’s master’s thesis project at Umeå University. It gained viral popularity on YouTube for its fluid, intuitive interface. Commercial Transition: In 2008, the project was taken over by Algoryx Simulation AB , a company founded by Ernerfeldt’s former supervisor.
