This was my first Glow Cloud cosplay. I wore it to the Welcome to Night Vale live show in Washington, DC, on April 19, 2016. Molly Quinn tweeted my cosplay. I also wore it to AwesomeCon 2016 and FlameCon 2016. (Cecil himself told me I did a great job and I almost died, okay.)
The main glow cloud is a parasol with addressable LEDs covered in polyfill. It runs on an Adafruit Pro Trinket and has a button to cycle through animations. The baby glow cloud is made of addressable LEDs inside a paper lantern covered in polyfill and runs on an Arduino Pro Mini.
