Steampunk typography with glowing amber energy tubes

brass, polished copper, and dark mahogany wood, giving them a vintage yet refined look. Glowing amber energy tubes run through the letters, illuminating the design like old industrial lamps. Some letters feature intricate clockwork mechanisms, exposed gears, and tiny steam vents releasing a soft mist. Others are transformed into antique bookshelves filled with dusty physics manuscripts and mysterious glowing orbs. The composition is enhanced with floating metallic pipes, rotating cogs, and delicate filigree engravings. The background has a moody, atmospheric gradient with subtle fog, emphasizing the intricate craftsmanship of the piece."
