We will see in the next chapter a way of making this look better.

The same points which were noted following the picture {\em photonburst}
in the previous section may be noted here.  Again the curvature of the gluons
commences in the clockwise sense here and in the counter-clockwise
orientation for {\it flipped} styles.  The following examples may prove helpful.
