This (þ Evans) is kind of interesting—a “VR” like headset for the Video iPod called “myvu”:

The cool geek factor makes me almost want to run out and buy one. However, following my “everything gets cheaper and better” rule I’ll wait, as I want at least twice the resolution in each dimension (it’s only 320×240) and preferably a little cheaper (it’s $USD 250). Still, if I can get my hands on one when I’m in Las Vegas (soon) you never know what may happen.
