USB Powered Rock

But what does it do? Does it DO anything? Or do you just plug a rock into your PC and it just sits there, all rock-like. At least make it sing.

I know it would ruin the link to the pet rock, but how about a nice had-warmer version. A nice warm rock to warm the fingers on might be good. Last week it was so cold at work I filled a coke can with hot water just to thaw out my stiff fingers.

james b gives me an idea - just put one of those little 'wifi detection' gadgets on the surface, instead of a cord, and you could have a wifi-detection rock. it's not AS ironic, but at least it'd have a use. (I think using a rock to detect signal strength would be quirky/novel enough. :P )

I remember the first time pet rocks were big. I'll go with the wireless rock from the yard, like last time.

This will really catch on soon as a bachelor thing to have. Nobody will actually get it (besides history geeks), but its perceived irony will certainly entertain.
