EDIT: I just renamed this thread as it evolves into a wave of primitives and patterns that all take part of something I would like to refer to as The LEGO Molecular System, with LEGO parts being the 'elements', the primitive compounds being the 'molecules' and the generated (potentially) infinite patterns being 'matter'. Of course these LEGO molecules may represent real molecular counterparts, but they don't need to. It's The LEGO Molecular System !
I've been intrigued by infinite patterns for whole my life and was looking for the smallest Technic primitive to create an infinite recurring pattern that is the same in all 3 dimensions. This is the smallest I could come up with:
It generates this pattern:
What is the smallest primitive that can generate an infinite recurring pattern that is the same in all 3 dimensions?
