Thanks a lot, y'all. There aren't many cats on the forum, let alone on the planet(!), that appreciate this stuff. It's just too much fun for me to keep it all to myself.
The volcano is definitely my favorite of the two. The inward taper going up from the bottom of the bowl makes for easy access to the switch and a very comfortable hand feel... and the lip around the bottom is just icing on the ergonomic cake. It's a tough shape to execute, but well worth the effort. I'll definitely be making more of that shape.
