The Portal 2 Inflatable Personality Cores from ThinkGeek are officially licensed collectibles based off of the Portal 2 video game characters Wheatley and Space Core. They are both available to purchase from ThinkGeek.
If you’ve always wanted your very own Personality Core, you’re in luck! Aperture Science has perfected the Inflatable Personality Core: all of the personality, none of the expensive metal and electronics! They’re perfect for hanging from rails on your ceiling, chatting you up while sitting on your desk, or convincing you to apply to be an astronaut.
