Seeing Double

This is a simple pattern yet it has some appeal. Although it seems like disconnected, the local patterns are connected.  The touching pentagons have the same orientation which means that a regular pentagon would fit between them.

Somehow the colouring I choose has an interesting effect of seeing double.  I originally choose the colours to visually explain that the touching pentagons are related by an invisible pentagon (not by an arbitrary angle).  Then I noticed this doubled effect was kind of cool.  Perhaps the two sizes of triangular gaps add a bit the distortion effect.  Whatever the biggest contributor to making this pattern interesting, I'm happy with the end product.
