I'm sorry but I'm not understanding what you are trying to do.

How is your ArrayRoll different than circular array?

Do you want the object to rotate in some way on every array step?

Kinda need some more details.

I'd look at using something like Gearotic for this. Or at least ask on the Gearotic forum if you want to roll your own.
