The Thotcon 0x9 badge this year included the Sparkfun ESP8266 Thing Dev board with WiFi and 8 I/O pins. The badge also included the DOGS102 LCD screen.

The Thotcon 0x9 game had 10 games on it including my favorite, Thotcon Plays Pokemon, a creative play on Twitch Plays Pokemon that used an IRC client on the badges as an interface to the game as it was projected on a wall at the conference.
