Now there are fish playing Street Fighter II on Twitch

We've seen plenty of unique livestreams on Twitch this year, including the original "Twitch Plays Pokemon" -- but "Fish Plays Street Fighter" is really something special. A camera captures where a couple of fish move in a tank, and converts their positions into moves in a game of Street Fighter II, allowing the fish to battle each other in the game. This isn't the first time fish have played a game on Twitch -- most recently "Fish Plays Pokemon" showed it was possible -- but "Fish Plays Street Fighter" is arguably the best use of the concept yet.
