Noel! thanks a for the code and comments on it. Great way of explaining it. The first time I saw it I thought it was too complex. I still think it is, hehe but after all the comments, yeah, I kinda grasping it.

I was super excited because after your first replied I thought “oh, it will be nice to make a qr code thingy” But, oh yeesh.  
Very interesting too, for me to see specified indexes at the arrays instead of filling it randomly like most tutorials I read or saw.

Thanks a lot, Noel!

The random walker idea might still be interesting

@Huno Yes, a random walker is a nice idea. I would like to see that.  
[Here’s a tutorial](https://happycoding.io/examples/processing/animation/random-walker) on Kevin’s site. A great place to hang around.  
I would add code keeping track of the distances between points for a more evenly distribution. (not packing) [Here is a tutorial](https://thecodingtrain.com/Tutorials/9-additional-topics/9.8-random-circles-with-no-overlap.html) about placing circles without overlapping on Daniel’s page.

please note that with that it looks better. It’s a **gray** outline for the rects.

(Without it, the outline would be black and the rects are also black, so we cannot distinguish between adjacent rects. That looks not as nice)
