Same setup. Different release.
Newton advances 12 isolated worlds on CPU. Two 1.6 m links per world, identical gravity, zero initial velocity. Only the starting angle changes.
samples per world, including the initial state. No policy or model call.

Twelve double pendulums. Almost the same release. Entirely different paths. Turn a recorded physics experiment into a motion sculpture you can explore.

Paused at the largest recorded separation. Replay to see how it began.
Walk around the experiment.
Motion overlay puts the recorded paths on the same axes. Time sculpture spreads samples along a depth axis: depth represents time, not physical travel. Trails end at the selected sample.
Drag sideways or use the camera buttons. Step, scrub or share the exact sample and world.
Take the motion into Blender.
Import scene.usdc and set Blender to 30 fps. The 24 animated links retain every source pose. World groups are spaced along Y for viewing.
