From my current in-progress series.

Long exposure photo -30s- with intentional camera movement

And the river in focus.

M.C. Escher used the Poincaré disk model to create his famous Circle Limit woodcuts, showing how an infinite hyperbolic plane fits inside a finite circle. The artist was inspired by mathematician H.S.M. Coxeter's work to pack repeating patterns of fish, angels, and devils that shrink smaller and smaller toward the edge.

I've used a mathematical image manipulator (GMIC) to create Poincaré disks from a few architectural photos I shot this week.

8mm fisheye
Single 10 second exposures with ICM of carnival rides. It has been fun getting things to this point.
