Mice have traditionally been two-dimensional creatures, offering an easy way to navigate around flat and boring desktops. Now that 3D is a new buzzword and everybody (and their parents) are cruising around Google Earth, it's time to take advantage of all those extra degrees of freedom.

We've had body fat scanning technology for a long time. It's called a mirror. If you want to get fancy, though, then you get this body volume index machine, a new 3D scanner that not only analyzes your amount of body fat, but where it is. Where it is could make all the difference.

If you think shoving 3D in every piece of gadgetry is the way to go this year, you may be right. This cellphone is one of the first non-smartphones that we've seen that supports 3D without glasses. Oh and it's super cheap!

You haven't seen 3D, even in a movie theater, until you've seen it through Runco's new D-73d projection system. And you probably won't ever see it since the projector costs $50,000. But if you happen to have that much spare cabbage laying around, you could buy yourself a 3D HDTV to end all 3D HDTVs.
