I can see why it should not work on cartesian printer.
But its very nice.
what about the part of the video which explicitly says it can work on a cartesian bot, with an image of a printrbot? 
Ehm, I stopped the video just before this part:) So its just stupid title.
Lol - so I can see it working better on a delta with higher speed Z moves, but as others have mentioned it would work on any 3D printer. You might think Terence had an agenda to push here.
