You don't have to be a fan of the puzzle-platformer 'Portal 2' to dig these Portal Personality Core rings, but it would definitely help. These rings are designed by Ammnra Props and are fashioned in the shape of the game's robots or personality cores.
Each robot in the game has a different personality derived from their respective cores. Ammnra Props' offers a Wheatley core, a Fact Core, Rick the Adventure Core along with several others. Each of the Portal Personality Core rings can be made out of a variety of materials and are priced from between $15 and $105. Portal fans are known for creating some truly awesome and geeky tributes. Here's hoping that other crafters are inspired by their favorite games to create more rings, bookends and earrings. The world needs more video game-themed everything.
