Can a single vertex be rotated? In the duplication options for the dupli verts there is a option for Rotation. Witch brings me to my question, is there anyway to rotate a vertex? Vertex's have normals, is there any way to control which way the normal of a single unconnected vertex points?
From the Blender wiki.


If the vertex pertains to one or more faces, its normal is the
interpolated value of all the normals of these faces.
If the vertex does not pertain to any face, its normal is aligned
with the line from the object’s Origin passing through this vertex.


On a unconnected vertex the normal will always point away from the object's origin. On a vertex connected with one or more faces (like stacker said) Vertex normals are interpolated from face normals.
