Garage Doors: Rectilinear Distinction

There are a host of just plain rectangles in Garageworld, but I like rare variations such as these.


Cells floating proudly with their skinny nuclei.



Reticent rectangles in chains.



Sticking close together for safety.



Offset randomly or by painstaking design?



Optically messing with your head - is this cruciform design just a big rectangle laid over a couple of long ones, or are those four petals surrounding it?



I don't know what this one is trying to tell me.
