People Playground

People Playground simulates ragdoll anatomy in enough detail that experiments here play out with real internal logic rather than a scripted animation, which is exactly what makes chaining tools together, a trap triggering a machine triggering an explosion, feel like genuine cause and effect.

Because the simulation reacts consistently to the same inputs, testing a new tool in isolation first before working it into a bigger combo tends to reveal exactly how it behaves, which then makes a multi-step contraption far more predictable to design than guessing at several unfamiliar tools at once. Melon Playground offers a lighter, more casual version of this same physics-sandbox experimentation.
