Rob,
Call me crazy but I actually like the red columns. I like the red color.
I have never seen this, but if you really really want to cover them up i wonder what a very thin curvbed glass block would look like around them.
If you didn't lile the poles and wanted to disguise them you could paint the pole white, drop in from the top some of that lighting that is like in a plastic tube, I forget the correct name for it. The light is real flexible and you can wrape it around things, and it has almost like Chrismas tree light bulbs inside.
Leave a little opening in the top in the back for pulling out the lighting and replacing it. But again I think the red pipes look very nice.
