How to create a flower unfurling effect? The effect I am looking for is not like a simple flower but more like a plant unfurling over it's length. Like This:



I am not a beginner with animation nodes but in figuring this out the greatest problem is I don't really know where and how to start.

Now to the question,
The effect is like the tip is moving forward while still unfurling.

So any help with understanding and executing this effect will be helpful.
Create a flower petal, use the object instancer node to duplicate it and connect it to a for loop. 

The key concept will be the following: Connect a Time Info into Animate Number nodes. Use this value to drive the Rotation and the Scale to make the petals flip open and "grow".
Now all object will flip open at the same time. To make them open one after each other, qdd the instance number to the Time Info.

The rest is just getting the proper timing, spacing and interpolation. 

This node setup should get you started.
