Randomize Scale & Rotation of an existing blocks based on their base points

Hi every one,the blocks are already in their places, they just need to be more random looking.
I would really appreciate your help.
I’m really just a beginner.

It seems like a job for Grasshopper. It does have a random function/component.

[I am going to look into making a Material coordinate h/v mapping randomizer at some point.]

I’ve already posted it in grasshopper forum too, hopefully someone will help…

Please do not double post. If this is the proper category, then please delete the other post.

Probably best to use a script (Grasshopper would require replacing blocks or putting the rotation into a script that affects the block in Rhino)
