a bit like gridcosm reversed a total of 5 squares of the 9 available can be edited to complete a "level" as the level is completed, edited areas are divided up into another nine areas that can be built on, kinda like lego. So all edits affect level 0 and each square that it resides on in increasing detail.

3D view would be possible by giving each pixel a depth of 1. An animation fly through morph would be insaine.
