Bending Bars

Ok, what I have done is created two bars, and I want to bend them so they wrap around eachother, kind of like a strand of DNA, but have absolutly no idea hot to do it. Can anyone please explain how to do this?

Something like the stem of the mushroom cloud in this image: http://outtie.home.comcast.net/poster008.jpg

Is that what you are talking about?

It's not too difficult. Basically you just bend your bars into symetrical "S" shapes, over lap them, then on each one mask out ever other crossover so it looks like one it passing over the other one - then behind it - then in front of it - etc. Add some shadow and highlight in the right places and that's about it.

Yeah, thats what I'm trying to do. But what you said made absolutly no sence to me. I've been working with photoshop for a while now, but had much time to get that far into it.

So, how would I go about doing this? How do I bend the actual bars?
