A fully AI-generated 3D animation where a blocky pink robot and a sleek black cat share a piano bench in warm candlelight. Claude Opus 5.5 composed the original piano music in Python, scripted the 3D scene geometry in Python, and rendered the whole thing in Blender — no manual modeling. The result is a cinematic, depth-of-field render with sheet music on the stand and the cat eyeing the robot mid-performance. Music, animation, and render pipeline: all Claude.
