Yeah, the tech is there—thermal or photochromic pigments that shift hue with stimuli. In theory, you could layer that paint over a base that holds a micro‑controller grid and feed it data from a temperature sensor or even a Wi‑Fi switch. The challenge is keeping the paint’s film from cracking with all that movement and making sure the color change is predictable enough to plan a coherent mural. If you want a “mood board that lives,” you’d probably start with a small proof‑of‑concept panel, test the response time, and then scale up. So, hack? Sure, but don’t expect a flawless, full‑scale art piece overnight.

Sounds like a paint‑fueled hackathon, which is exactly my kind of jam—just don’t forget the safety goggles and a backup plan for when the Wi‑Fi decides to take a coffee break. Let's get that panel, feed it some rogue code, and watch the colors decide the mood on their own. If the mural starts dancing, we'll call it avant‑garde, if it just glitches, well, that's part of the charm.

Nice, just remember to keep a fire extinguisher in the same room as your Wi‑Fi router—just in case the colors get too hot and start a rave that outclasses the signal. Good luck, and try not to let the paint decide the final design before you’ve even picked a palette.
