Forget the kids, I'm going to get one of these for myself!

Pros:
If the words "the first holographic thing you can hold in your hands" doesn't mean anything to you, then how about the fact that people can see that energy is matter. This is groundbreaking.
Great for visualization.

Cons:
Not sure if it belongs here, but I went to the website, wish they had better video showing this. Only pics of kids holding the hologram and some animated gifs.
