Mosaic 39: 2P vortex shedding

I decided to go a bit out of order, and knit 39 before 38, based on what yarn was readily available. Different people variously saw little men flexing their arms, trees and other designs in these socks, but I decided to name them after the most nerdy-2P vortexes. These were described in a 1988 paper by Williamson, who drew a schematic of it. I also found a picture of them here, in Figure 5E. I’m jealous that people studying fluids can take such pretty pictures of their experiments, while my solids aren’t as intrinsically visually appealing.

The green yarn is by zauberball, and the black is Opal.
