- OLED screens (flexible, printable -- this is already kind of a reality).
- Space Tourism (to Mars) - also becoming a reality.
- A Snow Crash-esque virtual world (sorry, most MMOs are not even close).
- Jetpacks (They exist, but are unwieldy and expensive)
- Dinosaurs (a la Jurassic Park)
- Flying Cars (they exist, but not yet cheap)
- Holograms (they exist, kind of)
- Hoverskate[board]s
- Futuristic Sports (like Speedball)
In the hunger games (good movie btw) there are windows that also function as screens. So the main character is looking out at this huge cityscape and suddenly the window turns into a screen with somebody video-calling her. I thought that was pretty cool.
