Hi HN, I'm Sten, one of the creators.

We built this because we wanted 3D experiences without needing a VR headset. The approach: use your webcam to track where you're looking, and adjust the 3D perspective to match.

Demo: https://portality.io/dragoncourtyard/ (Allow camera, move your head left/right)

It creates motion parallax - the same depth cue your brain uses when you look around a real object. Feels like looking through a window instead of at a flat screen.

Known limitations: - Only works for one viewer at a time - Needs decent lighting - Currently WebGL only

We're still figuring out where this is genuinely useful vs just a novelty. Gaming seems promising, also exploring education and product visualization.

Happy to answer questions!
