Brick Layers – Why did no one do this before? (3D Printing) [video]

An interesting problem for those who're good at e.g., geometric packing problems and space-filling curves.

I wonder about having an optional fill mode with more of a sphere-packing approach. I.e., instead of layering long threads of filament, what if you put down a bunch of dollop-drops in a checkerboard pattern and then staggered successive layers of dollops to fill the gaps?
