Rotate / Scale Randomly within Grid Structure

Hi there,

I’m really new to grasshopper so apologies in advance for asking a seemingly basic question.

I have created a pattern and mapped it to a grid to create varied outputs. At this stage I can’t seem to randomly rotate the pattern within the individual grid cell, I can rotate them all together but not independent of each other. In addition, I’m hoping to slightly vary the scale across the grid rather than a uniform output. Can anyone please share some advice on how to rotate grid cell data independent of each other?

I have attached my script, apologies I know its not the most efficient way to build it, I have also attached the precedent image for reference.

Thanks for your time,

Kind Regards

Thank you very much for your time. Also, I’ll be sure to look up some data matching tutorials online and getter a better understanding. Really appreciate the help. Thanks again
