pointProjection.py :
help you to find where is an animated (or not) 2d point in your 3d space and orient object according to the surface normal and direction of the motion. It s create an Axis that you can use to drive any 3d node in nuke.

current limitation :
the point position pass must be in world space
the normal pass must be in range -1:1
the direction of motion is experimental, you certainly must tweak the rotate Y of the Axis
have fun,
