I heard about this study in Nature (subscription required) in a recent talk. See some pictures here.
When a water jet strikes a flat surface at high Reynolds number, it normally creates a circular hydraulic jump. In the paper linked above, Ellegaard et al. demonstrate that stationary polygonal patterns can be formed (instead of circles) when high viscosity fluids are used.
Fascinating.

I did see that one a long time ago.
Great thoughts you got there, believe I may possibly try just some of it throughout my daily life.
