create string portrait

Hi guys, 

https://datagenetics.com/blog/december12019/index.html

I'm trying to recreate string portrait, but still in some problem I can't figure out.

Here's one of my though.

For detecting the best way to select the next point

1.create a circle with 200 points

2.split one of them and connect to others. Now I get 199 of line. For the first iteration. I start at pt0

3.resample all of them to 15 segments

4.attribute transfer from the grid with picture you want

 

5.get the minimum Cd from and blast it

6. get the point from the line

and connect to the start point

 

Then trying to repeat those nodes, but it don't work well.

They easily to get stuck in one line repeatly. e.g. pt0 - pt 100 - pt 150 - pt 100 - pt 150... and dead end

 

So maybe try to record the line which used before is a good way. 

Which one should I use, solver or for loop with feedback?

Any tips will be helpful. Thanks

Thanks for reply konstantin magnus 

It's great, but I don't think that's what I want.

The strings shouldn't turn back when string arrives the boundary of the font which is used in the linkpage.
The strings should go through until the pin then turn back. Finally draw the silhouette of the image.
