Twitch Plays X
In the wake of Twitch Plays Pokemon, I cranked out Twitch Plays X, a tool which allows you to create your own stream and receive input from the Twitch chat. There's no actual streaming capability built in, so you have to just point OBS at the window. It works, but if I recall, I set up a test stream of Pokemon Blue and amazingly like 10 people joined immediately and started playing. I came back a day later and it seemed the program had segfaulted, which I think I fixed, but I never really trial ran it again. The fonts are a little broken now on high DPI monitors.
