Gummy Bear Stacking Physics Simulation

A gummy bear physics animation: dozens of little bears pour into the frame, bouncing and squishing, piling higher and higher around one giant gummy bear. The original post was a screen recording comparing Opus 5.5 and GPT-6.1 Sol on the same prompt — the Opus version is busier and more chaotic, the GPT version tighter and more controlled. Good for fun physics shorts, model comparisons, or social clips.
