Here's multiblob for GridFlow.
http://gridflow.ca/gallery/multiblob.png
It's actually my own implementation: it's not been ported from anywhere else. Each cross is centered on the centroid (1st order moment) of its corresponding region ("blob"), and the size of the cross is the square root of the area of the region.
I will make another version which will use rotated rectangular crosses. The two lines of each cross will represent the two radiuses of the standard deviation of the region, and the angle will represent the angle of the standard deviation. I will use [#moment_polar], an abstraction based on [lti.Jacobi].
