A couple years ago I went to a small demo of a hologram machine called the Voxiebox[1] at a bar in Brooklyn. One of the prototype demos[2] was a voxel game called Voxatron[3] in real 3D. I was in an audience of maybe 5-10 people and the prototype machine was a little crude, but it felt like I was getting an early glimpse into the future of computers and gaming. The applications for this kind of tech are exciting to think about. Until that night I hadn't even imagined that holograms would ever become a reality, and I had also never heard of voxels. It really made an impression on me. I hope they succeed in making their machine viable for consumers because I could tell how passionate they are about it, and how hard they've been working.

How does it work? That website is... light on information.

  I was there too! It started back at our old Kinect hacking meetups :) I remember when these guys started meeting each other. Essentially, it is a display in a vacuum moving up and down really fast. I remember them talking about using either a display, or a solid color and a pico projector. Not sure which they actually went with.

    You were at the Barcade event? Small world.

  It's a swept-surface display, which is what you can see as arms blurring at the edge of the display volume. Essentially, the object to display is sliced up like you do for 3D printing, and a screen of some sort is moved to the lowest Z position, and the bottom slice is projected up onto it. Then, the screen increments it's Z position, and the next slice is displayed, repeating until the entire object has been displayed. Thanks to persistence of vision, it appears as though the image is 3D and floating.

    Good explanation.
