Another early spring flower

I keep noticing these small blue flowers which appear to be widespread in the neighborhood.  The flowers are only a few mm in diameter, but under the microscope they look lovely!  As nearly as I can tell they are a type of "Creeping Speedwell".  The images below were taken with my Nikon FS-2 using a new micrometer based system to get better resolution with my focus stacking.  Each of the photos was composed of over 30 individual images merged using Helicon Focus.

The photo above is fairly high resolution (click to enlarge), and the images below are side-by-side parallel 3D, followed by anaglyphs.
