Here is a blog post I just completed describing how I put together a few items to make an Apollo from Westcott, in this case the Orb, useful by making it tilt on a light stand.

You'll notice that my first approach was to use a grip arm. This is still a great approach if you also want to boom the Apollow away from the light stand.
The PCB Baby Boomer is the perfect solution if you want the Apollo to tilt on a light stand and also want a small kit that's easy to pack up and transport.
