  Rewrite preparation for 0.65

export the eye group origin as "eye.location", and fly group origin as "fly.location"
add a "rotation" layer to your eye group,
convert it's amount (angle) to "vector angle" and then convert this vector to "subtract".
link LHS to "fly.location" and RHS to "eye.location".

you can now freely move both the eye and the fly... and keep a close watch on the pest
