3-D Twist in Illustrator

[nukerdoggie]

I'd like to create a twisted 3-D ribbon-like structure - as if you held a flat ribbon at its two ends and twisted it in opposite directions with your two hands.

I can create the ribbon but the "twist" effect appears to happen in only one dimension, or maybe two. I'm looking for that 3-D DNA model look, with the winding staircase appearance.

Can this be done in Illustrator CS?

Thanks,

Nukerdoggie
