Is it possible to build hyperlink to each node?

It is possible, but it need a little work...

Here's the recipe :

1. define a flexinode to define a node with a field that contains the data to display;
2. figure out (by looking at the data in the database) what's the flexinode field name for that field (should be something like "flexinode_2")
3. go into taxonomy_ticker.module and uncomment & modify the code that's in there (look out for some commented code ... you should see "flexinode_2" in there already). Here is the line you need to modify : $block .= "<div class=\"scrollerContentItem\"><p>$node->flexinode_2</p></div>";

We coded this module for that specific need and we got it to work... but we were in a hurry, which explains (although it doesn't excuse) why we hardcoded the flexinode_2 field.

I hope I'm not forgetting anything, that was last autumn... I also hope that flexinode hasn't changed too much in 4.7.

I would be very grateful to anyone providing some clean code for all of this.

Oops, I just re-read your post ... and I just understood the problem. You're right, I'll look into that...
