The following (including music) is entirely the product of computer algorithms; a.k.a. procedurally generated content:

We’re getting closer to good brain-interfaces:

I think that the above video is the equivalent of watching a tech demo of cell phones in the late 1980s. Give it 20 years and it’ll be everywhere, give it 40 years and it’ll be unthinkable to control a computer with something other than the brain.

Other things that have been exiting for me:
* Exoplanets
* Exoskeletons
* Netbooks (more)

Take note: The collision between cellphones and personal computers is happening. A good amount of resistance to adopting netbooks probably comes from PC gaming (it certainly does for me) and lack of good cloud-based applications. These problems are being solved though, and I anticipate a full integration by 2015.

EDIT: Oh! I forgot this one!
