Hey. So here's another update to the 2D sprite module (named Sprites).
Just a slight bug fix, but also, I've included an example in which a 2D sprite (an arrow) follows a 3D object, changing sprites when necessary to face the object.
By the way, I included two copies of the Sprites module in the download, but they're the same.
You can download it here.

EDIT: There's a slight bug in the script - replace it with the one found here.
