What do you want to see [innovation-wise] before you die?

I'm an Iron Man fan, and ever since I saw the first movie I've been hoping that I'd see the free-floating holographic technology he uses. I have seen the beginnings of it, a machine in a room that ignites photons in mid-air making rough outlines of shapes and objects. But it's extremely dangerous and impractical right now.

One of those transparent computer screens would be cool too

Lightsaber
Speeder bikes
Bio mechanical enhancements

Seriously where are the hovercars toyota made back in the 80's that used electro magnetic disks instead of wheels?....

And where are the droids I'm looking for?

The only thing I would like to see is the end of discrimination, in whatever variety it may be experienced in. When we get to the point that we accept each other "as is" many of the inventions listed here will be a reality.
