Minecraft on Hololens video (3-D Hologram)

I haven't seen this posted yet. So far this is the most impressive thing I've seen at E3 this year. If it works like it does in the video, then by far this is one of the most impressive things I've seen in my life.

Not just because of Minecraft.

The implications of this kind of technology are endless. For instance I've always wanted to learn how to rebuild an engine. With this kind of tech I can learn the fundamentals on how to do it.
