You start thinking that the science fiction story you just read or movie you just saw is maybe in reach. Maybe it’s possible. For example, in the movie Prometheus, they have these flying spheres that go up and down caves and use laser tomography to map their structure. We don’t have that, but that’s really cool and I can imagine having that.

That idea might inspire me to try and create it instead of just sitting back and saying, “Oh, that’s the future and it will probably never happen. Now let me go back and watch Snooki.”
