Blotting Stones was an idea back in 2016, at the time I drew it in Illustrator and then tried to animate it with a combination of Illustrator and Photoshop. That turned out to a jumpy animation as seen here: ‘Blotting Stones (2016)’

Here’s my re-attempt at this in 2021 using Adobe Illustrator and After Effects. The full size version is 4K.
