Want a ramp? Scribble a line. Want a box? Draw a rectangle. Want water? Grab the fluid brush. Everything you create instantly has mass, collision, and reaction to forces.

Let’s dig into the history, the magic, and why you should download it right now. The story begins at Umeå University in Sweden. A master’s student named Emil Ernerfeldt wanted to create a real-time 2D physics sandbox that felt like drawing on a whiteboard—only everything you drew obeyed gravity, friction, restitution, and density. phun algodoo

The community exploded. Suddenly, teenagers were building working gear trains, marble machines, catapults, and hydraulic lifts—all in a free, lightweight program. In 2008, the team behind Phun founded and released a polished, professional version named Algodoo (a playful mix of "Algoryx" and "Phun"). Want a ramp

Today, Algodoo is used in classrooms from middle school to university. But it has never lost its original, joyful weirdness. Here’s what makes Algodoo different from every other physics simulator (including expensive ones like MATLAB/Simulink or even PhET): Draw a rectangle

Phun was a gift. Algodoo is that gift, polished and expanded. Whether you’re a teacher tired of static diagrams, a parent looking for screen time with substance, or just someone who wants to build a giant domino topple for no reason—

He called it . The name was perfect. It was phun.

At first glance, Algodoo looks like a toy—a colorful, 2D playground for bouncing balls and crashing cars. But after spending a decade away from it and coming back as an adult, I’ve realized something surprising:
