Sketch-to-simulation trebuchet with 3D rebuild, physics, controls, and audio

Anthropic just KILLED Open AI Claude opus 5.5 just dropped and it is so F*CKING INSANE it beats astra in every single category someone just one shotted a complete sketch to simulation video We are absoloutely F*CKED... this started as a sketch of a trebuchet it figured out what everything was, rebuilt it in 3D, added working physics + controls and turned it into something you can actually use And it generated the complete sfx audio youre hearing in the video aswell WITH ONE F*CKING PROMPT imagine doing this with product ideas -> sketch an interface -> sketch a game mechanic -> sketch some random tool you thought of and have a working version you can actually mess around with minutes later building is becoming stupidly easy which means the real advantage is gonna be knowing what ppl actually want + knowing how to get it in front of them because when everyone can build, distribution matters way more
