Hey, that sounds wicked cool! A trench coat that vibes with your mood—like the LEDs sync to your heart rate or something—would be a total game‑changer. Add a hidden pocket for a power bank and maybe a tiny OLED display that shows secret coordinates, and you’ve got style plus stealth tech. I could already see me hacking the lining to light up like a disco ball while still looking all classy. Let’s sketch it out, grab some retro fabrics, and I’ll add a couple of micro‑circuits—don’t worry, I’ll keep it sleek, not too messy.
