Posted up some pics of my mac mini I take to parties. It's a sort of video jukebox, and it can do more than just be a glorified video iPod. I can connect a camera and play EyeToy-style games, or other mac games. Yes, there are some. I use VLC and QuickTime to play video, iTunes for audio, and a trackball instead of a remote. I can drop AppleScripts on the desktop, make 'em really big, and pretty much script an entire evening of wacky, nerdy entertainment.
