To the newcomers: there are two videos! Don't forget to see the video from the first post below too!
Here is a video of the demo loop of Quake. The video is a little more stable because my hands weren’t shaking it while I was playing like the other one. Actually the video from before it was actually playable because I didn't have the client side of the code working yet. Enjoy...
Edit: It seems its twice as long as it should be, I'll repost another video later.
