A glorious project has seen it's conclusion over on Deviant Art from Element0fKindness. Twilight Sparkle's cutie mark has been hoisted to thee air on a 20 feet tall, 13 feet wide frame with a whopping 1,425 LEDs woven throughout. That's 70 lbs altogether. It now hangs hoisted 75 feet off the ground for all the world to see, or at least the nearby highway.
I better see a lot of Christmas light ponies this year.
