A few weeks ago @notjustbikes released a video on Klinkers, the standardized bricks used for paving in the Netherlands. Today, on a bike ride near Sint Michielsgestel (near 's-Hertogenbosch), I found odd 'ribbed' klinkers used as lane markers in the bike lane.
Just because I'm a weirdo, I made a 3D model of the klinker, and subsequently an animation of it.
