How can I run a portion of the network iteratively?

I am trying to do cmivfx's hip tricks 2 where they are showing how to make a game like this:

More info on the game:

But he is using a 3rd party HDA called sop solver, where I want to do it out of the box. Basically the part where he group the connected portion starting from the top left corner with the same color. He does it at every frame and changing the color as he goes along by overriding a custom attribute.

I have all of this too, but how can I run the portion that does this so it does it iteratively.

I am also not sure how the sop solver works frame by frame while the assigned color changes, I mean where is the histroy of colors are saved.

Does it make sense?

Thanks

Hey Ryan, haven't seen the vid, but sop solvers aren't 3rd party - they're a totally in-the-box part of dops, and are the best way of doing geo with feedback / history in houdini. Peter quint has some good videos on how to use them:

Feedback can also be faked with for-each sops, but the logic tends to get a little more fiddly.

Thanks, I didn't know that. The author asked to use this tool in the video:

Will see if I can do it using the methods you mentioned, since I haven't used DOPs much.
