Interesting, this in combo with a single engine taxi pretty clearly explains what the OP observed. From the info I've very quickly gathered, part of the role of the inlet guide vanes is to support the shaft. I would assume that all jet engines must have a stationary structure somewhere in them for shaft support, but the unique (or unusual) thing with the JT-8D is that it is forward of all the compressor blades.

This is clearly what I was seeing and makes some sense now based on your explanation. I guess I'm too used to the 737s where the front blades spin.

I finally got the picture uploaded of the blades standing still while on final (over the water coming in to LGA) if anyone wants to see it. Click here.
