This first pattern using the connection that hold 3 tiles off of it, shows the front and backsides of the pattern. The goal of this pattern was to create a system where both the front and back were connected together by hub pieces.
This second pattern shows a more visually random pattern within the backside of the system, although currently there is a pattern within this system.
This third pattern shows an attempt at keeping the backside connected by hubs to some extent while still trying to break away and have a free form. At this scale a pattern in what protrudes in the front side starts to appear.
