Also, light-up Black Panther + Ragnarok Thor:
This Thor by Cheyenne was so awesome! Costume was gorgeous plus smoke AND light up eyes! Light up eye effect = UV leds mounted in her helmet to make her contacts glow. Using @adafruit Gemma M0 and programmed with #CircuitPython Incredible!!! pic.twitter.com/OlKTk4z0Rh— sophy wong (@sophywong) March 17, 2019
