What – you haven’t started thinking about what you want for Christmas yet?

I want a 3D printer.  3D is not some passing fad.  Go to the Noel Leeming website and it’s a category under printers :-)  You can get one for $2K.  They were advertising them in the junk mail we got last week.  But the 3D printer I want is this one – it builds houses (in 24 hours) using fast drying concrete.  Watch the YouTube video if you want to see how it works.  Imagine what you could build if you weren’t constrained……..
