This is INX — Interactive Narrated Experiences, built by @4klabsai .

This cyclohexane chair-flip isn't hand-animated. It's code-generated, in 3D, and students can rotate it, flip it, interact with it directly instead of memorizing a flat drawing.

This isn't a video. It's INX — an Interactive Narrated Experience on electromagnetic waves, built by agents at @4klabsai.
