Well here's something we've seen before, yet better. This is a video of a Half Life 2 mod that incorporates Wii remote controls into the game, which we've seen before. This one is different however because this computer programmer type guy put the Wii remote driver right into the game instead of using glovePIE or some such stuff. It also incorporates the Wii Nunchuck to full use as well.
Now that I've said my nicy nice things about it, I also want to point out that the first half of the video has the most annoying song ever recorded by humans. I say only the first half, because I jammed pointy sticks into my ears, to stop the maddening sound from entering my brain, half way through the video. It is awful. Awful, awful, aawwfulll.
Pat hangs out at Half Life 2 World, and he wrote a thread detailing his work on this. Oddly enough, he doesn't seem to have a website dedicated to his escapades as is usual for computer tinkers of his sort.
