Because my post yesterday[1] got such great feedback, I turned my first twitch stream back on. This is Pokémon Showdown, an online Pokémon battle simulator. You can make moves with Twitch Chat. Be sure to turn up your volume to hear the announcer!

You can find it on github at https://github.com/adenta/showdown_realtime.
