Phun

About

Phun started as a Master's thesis project by Emil Ernerfeldt before becoming a standalone sandbox physics game. You draw shapes, assign them properties like mass or friction, and let the simulation run to see how they interact. The tools let you build complex contraptions and test their stability in real time without needing a degree in engineering. It runs on PC, Linux, and Mac systems. The title never reached a full release because it evolved into Algodoo in 2009, yet the open beta remains popular for its raw approach to mechanics. Players often share their creations online to show off elaborate Rube Goldberg machines or chaotic destruction scenarios. This legacy version keeps the original spirit alive for those who want to tinker with physics without extra fluff. It serves as a great tool for learning basic concepts through direct manipulation.
