@laurent_delrieu your definition could work too + @jopsa2 gradual deformation.
For images should be a real ellipse packing, that the ellipse direction could respond and align to some RGB value or something and 4 radii(min-max length and size) in order to have ellipses as circles too.
Hi, @DanielPiker could this be implemented in a custom goal a kind of LineCollider?
