Claude turns a black hole demo into a text-eating webpage

A user describes Claude unexpectedly generating a fully interactive black-hole webpage after being asked about 3D celestial bodies.
- The demo includes realistic-looking light bending and pixel-by-pixel geodesics.
- The standout detail is the input box: text you type spirals downward, turns red, slows, and disappears like it is being pulled into the black hole.
- Claude also apparently blended the idea with a previous project and then produced deployment instructions for the site.
