Finally decided to buy a Trent Bosch video rig for hollowing when I was at Portland AAW.
It's taken a bit of modification to adapt it to my Kobra hollowing set , but now it's doing just fine.
Have to say this is a huge improvement over the old laser pointer. One big difference is that the picture and cutter location are not effected by vibration whereas the laser would jiggle and bounce. Other major is that it's completely accurate when hollowing at the bottom of the jar where the laser was not very good. Makes a big difference in getting a uniform wall thickness all the way to the bottom.

Not being a turner, I don't know what is going on here, but I'm guessing it is a camera that projects on a screen places you cannot easily see. I had a colonoscopy earlier today, and I suspect there may be similar technology involved here?

I'm a little curious, too. It looks like the camera is just overhead (bird's-eye view), though if there were a digital overlay onscreen of the hollowing tool, or crosshairs of the tip of the tool, then I could see how it would work very well.
I don't think a borescope-type camera would be of much benefit while turning, though could be useful for inspecting the interior on occasion with the lathe off.

#5Saaay, Mark, you could set up your laptop to direct the lathe tools, kinda like a CNC setup, push the button and go upstairs and have a beer and a sammich while technology creates 'art'.

Nah. T'aint "art" in hollowing; that's just work. Art, if any, is in the shape and celebration of the grain and color.
Hollowing with the laser rig was "ok" but not always stupid-proof
