Ripples in water, undulating images, reflecting floating homes in Vancouver and Victoria.
The corrugated metal siding of a floating home reflects in Vancouver harbour at Granville Island.
The yellow fence of a floating home reflected in Victoria harbour.
To see some amazing undulations in solid rock, both located in Arizona:
Lower Antelope Canyon in Arizona
the red sandstone formations at the Wave in Arizona

I thought for a second that was the metal work on a Japanese knife…lovely!
Do you have a Japanese knife etched like this? If you do I would love to see it!
not yet…it is on ‘my list’ and my birthday is coming up soon 😉
We have a knife shop here in Calgary that sells amazing etched Japanese knives…they are called knifewear. Look them up and you’ll see! They are amazingly sharp. I could possibly cut a finger tip off with one.
