From yesterday’s post, I will just consider the possibilities of having 4 HD cameras at the 4 corners of the back of your smartphone.  The first thing I can think of with this configuration is the ability to capture and quantify small objects in 3D.  Simply hold the phone within a certain distance of a small object and sampling from all 4 cameras, the phone would easily be able to determine the 3D layout of whatever the object was.  Using existing technolog combined in this way, such a device could easily find accurate sizes and quantities of whatever it was capturing.

Imagine the combination of such a “scanning” function with a 3D printing device, and you could literally capture the 3D image of a trinket on the street in Korea, and in moments be printing out an exact replica for you back home in New York.   The fact that it can indeed be incorporated into smartphones makes it a wild technological advancement when you consider the potential database of everyone’s captures.

Oh geez, my brain has me on a roll of thought, as tomorrow’s idea should demonstrate.  Let’s take it a step further!
