Option 1 may fix the currently colliding flowers, but may create new 
collisions to take their place.

Option 3 is part of a solution I've got working in the back of my brain 
(see my latest blog post on my website).  For most scenes in my movie, 
the flowers will either be behind a wall of focal blur or zipping past 
the camera fairly quickly, so I may not worry too much about collisions.

Thanks for the suggestions :)
