Use Game Center much? Some potential patents Apple has filed for may hint at more robust features coming to the platform in the future -- specifically, avatars. Apple's documents (via AppleInsider) show customization options and fully animated avatars akin to Nintendo's Miis or Microsoft Xbox 360 avatars, which the company is apparently aiming to incorporate into Game Center.
The patents were originally filed in April of this year and talk about the usual rigmarole that comes with avatars, such as funny hats. There's also the possibility for these avatars to appear in games, Apple noted in the filings.
