3D Printing Your Big Data for Understanding

In Technology Review: Fascinating idea. As 3D printing becomes cheaper, you can quickly create a 3D physical data representation. (You can add more 'Ds' with indicators like color or shape). We did this for displaying real spaces, like retail stores, then overlaying other data, and discovered interacting with the tactile display resulted in better agreement on design than with a screen display. You can touch your decision. Shake hands with the data! Course you can touch the data, but not interact with it in usual way.  Still don't see it as a common approach.
