NB 3-4 appears to resemble the clone generated from NB 4-4.

This clone also has a PNS sub-clone, which we do not observe to be an obligate part of the lineage.

This movie is a stereo image of NB 3-4 clones.

3D glasses will enhance the stereo optics, but we find that most viewers can see the three dimensionality at this magnification without the assistance of the glasses.
