When I first started teaching I was using the "bander" machine to make copies of worksheets for my students. Next was a black and white dot matrix printer. The most used printing machine today is still the black and white laser printer but I now have a choice of printing in colour too!  What is even more exciting is the next step in development which is the 3D printer AND 3D pens. Check out "the 3 doodler" which is virtually drawing in the air. The possibilities of creativity something tangible is endless. For people who claim they can't draw, you can trace images in 2D and then construct them to be 3D.  Technology is awesome.  I wonder what is going to be next?
