For this AnimationNode experiment I made growing vines out of vertices using random 2d noise patterns. I used a grid mesh to generate the inital vertices and iterate over the list of vertices in the mesh using a loop. Then I used a second loop to generate the spline for each vertex.
The number of vertices in each spline is controlled by the framerate and each vertex is moved by a random amount along the x- and y-axis.
The node setup is a bit too complicated for a screenshot but you can download the blend file here
