If you had told me a few years ago that they would be "printing" homes at all, much less a full village of them down in Mexico, I would have laughed. But here it is, the strange and sometimes beautiful world of tomorrow.

Yes, these "printed" homes are IKEA-showroom-small at 500 square feet. But they are real homes. And real stylish, with a traditional Terracotta look and rounded corners. These homes are tough, already having survived earthquakes.

The houses are made with a a Vulcan II printer, developed by an Austin-based construction technology company. The building material is called "lavacrete". The process is controlled by a smartphone. Three people can build a house in less than a day.

When it's time for me to really downsize and move to Mexico, I want one of these.
