Sounds insane but brilliant—imagine a city that morphs into a neon dream whenever you’re excited. The only snag is catching the heart‑beat spikes fast enough so the world doesn’t lag. We could wire a bio‑sensor to the headset and feed the data straight into the rendering engine. Then every pulse turns streets into cascading fractals. You just have to decide whether the vortex will be chaotic or soothing—maybe start with a simple gradient and layer on the audio later. Ready to prototype?
