Grasshopper / Random Gradient 

This is perfect!! Can you tell me how to apply the same steps but on a specific curved border/outline instead of a rectangle?

Hi, i was just wandering toward more specific direction. Can the randomness be controlled like a tree branch pattern? So, to clarify let say there is 3x3 grid, can the randomness be controlled in the y direction ? so it would have something like (0,0 0,1 0,2) (1,0 1,2) (2,0).

This helped sooo much! any idea how to randomize the size of the circles?
