As suggested by OzPiper, here are two of my favourite "innovative" system pipes.
The first is the Jima, a plastic and metal body, with a clay bowl
The system is a hollow tube, basically:
Within that tube is an "electrostatic" filter, basically just a tight coil of wire. It is impossible to run a pipe cleaner through it, but the system actually does work, and I've never had a gurgle. The filters are meant to be replaced frequently (so I don't actually use one most of the time as they are difficult to find today).
The second is the Monarch, made by the same people who later made the Aerosphere and the Magic Inch
It has a metal, screw in tank. It is actually screwed into the briar, and thus the female end is on the stem:
The stem has an air intake valve, and a large reservoir. So the smoke runs through the metal tank, mixes with a shot of air, and the moisture is meant to collect in the reservoir. When I first used it, I noticed it leaked a bit, but a little PTFE tape on the threads fixed it.
Both of these systems actually work, but they are a lot more complicated to clean.
