That sounds like the dream of every home‑cinema nerd! Imagine a room where every wall becomes a 3‑D canvas and the speakers pop out of the floor. In theory you’d need a lightfield projector that can render multiple viewpoints in real time, plus a 360° acoustic array that tracks head position and shifts sound accordingly. The tech exists in labs, but turning it into a DIY living‑room set‑up? You’d be juggling lenslet arrays, adaptive optics, latency‑free rendering pipelines, and a room‑sized microphone array. Also think about power consumption, heat dissipation, and the fact that our brains can only process so much depth cue before we start feeling dizzy. If you’re up for a multi‑person, multi‑disciplinary project, go for it—just keep the room acoustics in mind, or you’ll end up with a surround‑sound nightmare. But hey, the future of home cinema is about making the viewer feel like they’re in the movie, so why not push the limits? Just remember to start with a small prototype and iterate—no one wants to build a full‑body theater before they’ve figured out the basic 3‑D overlay.
