In addition to some cosmetic tweaks to my Fallout raider cosplay, I've disassembled, repainted/stenciled and weathered the Fallout 4 "Pipboy edition" into a Vault-tec colored wearable prop. I wore it to FanExpo Toronto.
Here's an in-universe bio I wrote for this piece:
"Congratulations citizen! You've been randomly selected to receive a special blue, yellow and grey Vault-tec branded pipboy! This certainly isn't part of a nefarious social experiment wherein your overseer monitors the effects of social exclusion and jealousy surrounding perceived social difference. No sir! Anyone who said that is a liar, and should be reported immediately to your overseer. Enjoy strolling about your vault in style, with Vault-tec brand pipboy! Stylish and elegant: you'll be the talk of the community!"
