I saw some drawings on Instagram made by a friend @richardbriggs_artist , of the movement of a car over a bumpy road in Bolivia. It prompted me to pull out my own drawings made just over a year ago recording waves lapping my feet on a rising and a falling tide on the south coast of New South Wales.
I steadily drew a line back and forth across the page and if a wave washed over my feet I drew it as a peak, for the duration of it’s ebb and flow.
This is a continuous line drawing at the same location.
PS lest you think that I am even more of a tide nerd than I am, the details on the page were copied from a tide guide at the Ranger station at our campground.
