Game Boy Color on My Conference Badge

At GitHub Universe, the conference badge is a full color-screen computer, and Steve Francia used Gemini to get a full NES emulator running on it and then deployed emulators for both the Game Boy and Game Boy Color. With a ROM, you can run The Legend of Zelda: Link's Awakening on the badge. The badge can be turned upside down to use game controller touch buttons built into its body.
