Heptagonal flower

I was playing around with TileLand and I stumbled on some local patterns that I turned into this picture. It seems to suggest a lot of lines and make it hard to decide what you should focus on: flowers, rounded triangles (Reuleaux triangle), or triplets of arrow heads. 
     The way I generate the pattern is by connected paths heptagons an triangles.  I'll take a step back and see if I can come up with some ideas about this pattern.    With a regular polygon focus I have ways of describing the connection between the two types of loops and simpler patterns....  I'll keep you posted.
    This extra colour makes it a little more interesting perhaps...
