rotate along path

Hi,

I would create a wire text made of triangles, where each one is rotated according to the direction of the path.
Actually I used a text field+resample+polygon but how to tell nodebox to rotatet each polygon?
I attached a screenshot to better explain what actually have. Hope it's clear.

in the meantime I figured it out in this way, but maybe there'one more accurate.

There's a shape_on_path node that does this. Attached is an example.

urgh, thank you... feel so stupid :)
