What is the big deal about 3D? My only experience with 3D was at least twenty years ago when I rented a porn video that was in 3D. I don't know what I was expecting, but I remember being sorely disappointed. Since then, despite a rather generous but sporadic number of offerings in mainstream cinema, I have never seen another thing in 3D.

Lately, though, it seems that there has been a resurgence in the popularity of this genre. But it's not limited to movies, although the new Charlie Brown movie is getting a great deal of pre-release advertising. One of the hottest things in the 3D arsenal is the 3D printer. Now, I have no idea how this works or why one would need it. I assume that the detail in whatever is being printed would be considerably clearer and I'm certain that it wouldn't be used for a Word document. I saw a 3D printer on sale at a Barnes & Noble bookstore yesterday. It was more than three hundred dollars, and I can't imagine what your average book customer would need with such a contraption.

Who would use one of these? It can't be the average homeowner or even small business owner. Perhaps it has some value in scientific applications, but I have no idea. I guess it's another one of those things that keeps me in the dark ages. Heck, I just got my first cell phone in July of this year. I like to try to stay current on things, but this 3D thing really has me perplexed.
