Those are Dimension's original trekking bars, unfortunately discontinued (their current offerings are the conventional butterfly style). Can't seem to find any images on the net of the old ones. I had a couple of Electra Townies set up with them, they looked and worked beautifully on a cruiser.

I still have a couple pairs laying around, PM me if interested.

Just fyi, that picture in Xootr's gallery is of the maxed-out Swift built by bikeforums member "xootr swift". His original post about it was here. He used to have a Myspace page devoted to the build, unfortunately looks like it's been deleted.
