Paul better to catch the boat late, then to miss it altogether!
I picked up an articulating arm in Germany back in the 90s.
Likewise, I had never seen one until this Japanese photographer pulled one out of he 100+L photog backpack. I had to ask what the thing was...of course we were unable to communicate due to the language barrier. But, I took a shot of his "magic arm" and went off in search of one. They are great gadgets to have in the bag.
You're only limited by your imagination where to affix the arm for your next shot!
