The Cryonist's Guide to the Future

I could imagine an underground facility filled with thousands of heads, frozen heads just waiting to be reanimated. It reminds me of something like Futurama. And then they bring them back and they're on these little floating devices. They're just heads floating around all over the place. The more you think about it, the more creepy it gets really. But I mean, that's maybe just me being a pessimist.
