The way I have developed spirals is in Adobe Illustrator (there is a
spiral
tool), then export as .wmf and insert into PowerPoint.
Ah, thanks for the reminder; I'd meant to test this here too.

Whatcha know. Try using the spiral tool then copy/pasting into PPT.
Paste Special, as EMF.
When I do this with Corel Draw's spirals (it has a tool too), I get a
picture
that ungroups into a curve that I can use Edit Points on in PPT.
