Righto, it seems to be just the ticket. I don't know how I didn't see it before. This is elegent stuff.

However how do I put error checking into After and Before? I seem to be thrashing with nulls a bit.

				'gather 4 points needed
				p2 = tPoint(p.After())
				p3 = tPoint(p2.After())
				p4 = tPoint(p3.After())

Seems to throw an error when I get to the end of the list. I tried going checking for null but it up ends anyway...

Thank you for helping though!
