Recently, while idling around on twitch, I found a guy who does live coding for a unity 3d game. Not only that you can watch him code, you can play WHILE he's coding. Its a twitch based game, which means you can play your character via the chat on his stream and watch the result of your commands actions in the stream. He seems to be live almost every evening around 6:30pm (GMT +2). Check his livestream out on twitch.

What I really like about this stream is that zerratar answers your questions immediately and develops with much effort while still communicating with his viewers (whom's count is pretty low til now).
