Because Minecraft wasn’t already cause enough for procrastination: Programmer and player sk89q and his associates hacked the map added in the 1.6 update to play YouTube videos in-game. Notch: “Oh. My. God. Have all my upvotes!!”
This is indeed playing YouTube (over SMP — no client mod). The Mirror’s Edge video, however, was local. The sound is external. There is even, yes, a mapsaver (screensaver)!
Fraps dropped frame rate substantially so the video is not as smooth as it really is usually.
How I am doing this is unrealistic. However, I’m investigating the real possibility of a YouTube player.
THANKS to dested (especially), fullwall, and Tahg!
