As a Challenge, over the last few weeks I have decided to work on a editor similar to Fez's Trixel Editor/Cube Carver.
As an added challenge I have also tried creating this tool without looking to much into different solutions/algorithm to see if the knowledge I have acquired was enough.
So far its proved to work, the above gif is glitch but a good glitch that shows the process my algorithm simplifying one of the faces of a Cubil (original i know). From here I have to assign 5 more faces aswell as textures to each face
