Looks to me as if it's going to just keep on "walking" the way it's going, too. New pseudobulbs will form in line with the ones you already have. So plan on something quite long for it to grow in. Or on. A rough plank might be very nice looking. Or something like this:
It's a slightly rolled up piece of cork bark. You might be able to find cork at a nursery, or pet supply store. People who keep things like lizards use it.
