That one is pretty interesting in that he shows how to use vertex 
shaders. I also found this one which has a (OS/X only unfortunately) 
nice demo program:

I think he is mistaken about using this for triangles, but the ability 
to do round line caps and joins looks clever, and the use of a mipmap 
texture rather than a shader too.
