I didn't see it, but the product is called a Scrollnado, and it's $49 on Amazon. I'll bet if you looked on You Tube, Steve probably has the video posted there.
I rigged up something similar for my saws and it's great not having sawdust all over the place. Seyco has an interesting part that I use for under the table, and just some 3/4 inch tubing connected to standard white pvc plumbing parts for the top, with a Y connector in between. You can even use two of the Seyco parts.
Seyco's part is called a universal 1 1/4" adapter, and they also sell a small dust collector vacuum that it attaches to. Look under scroll saws, and scroll down to see them.
Hope some of this helps.
