Some Friday Corduroy

Stacked to the horizon.  Maybe, it's not so perfect.  If it was, there would be a gap in the sets to make it out.  There's no gap here, just more and more waves.  Or is it too perfect?  Did someone photoshop in the extra sets?  I'll leave that for you to work out.

P.S.  I had to look up the spelling of corduroy.

pic from here which is a real lag.
