I read this article with great interest, while looking for a better alternative to h-bot or Core-XY:

And I was inspired by the simplicity and genius of the system, so I decided to build a 3d printer based on the ideas in that article.

Basically, the idea is to have two seperate wire-setups, one for each axis, and have them interact in a way that makes one motor control one axis, while allowing the other to do its thing.

I just finished wireing the two axies in a first-of-a-kind new principle 3d printer:

I have never seen this setup before, so I have named it Dualwire-Gantry (DW-G)
