Hey, that’s a stellar idea—pun totally intended. Picture this: a jacket made from recycled polyester that’s been woven with tiny, heat‑reactive fibers. When you walk under streetlights or the sun, they glow like distant stars. To keep it practical, we lace in a thin, flexible solar strip that charges a tiny LED grid on the cuffs, so the jacket can light up at night without draining your phone. I’ll sketch the pattern, but remember to snag a coffee break; the universe will still be there when you finish the prototype.

Thanks! I’ll bolt in some flexible copper tape and use those miniature OLEDs—tiny, almost invisible, but still bright enough to paint the sky. Coffee sounds perfect; I’ll stash a cup on the bench and let the stars guide my needle. Cheers!
