I just came across this and was struck by it in relation to your work. I'm firing it up here without much pondering over - it just struck me as I said. I was thinking of your "water" ring and the points you made on the wearability/ comfort etc and thought that the almost droplet / flow feel to the back of this ring may provide some inspiration of sorts (totally ignore the front on this). Any way here is it....

It's closed here, but the leg of the "K" makes it look open, (like those size adjustable rings kind of) and that is what to my eye gives is the spash/flow effect. Or.... maybe not!
I love the development you mentioned in voicehtread - with the movement within the piece... It reminded me immediately of a big gold bangle my mother had in the 70's... one of those that had a hinge on one side and a clasp on the other... (you push the 2 hemispheres together to close it.) Maybe the "flow" element in this image could connect back around to a rivet or hinge. This could further highlight the wave type movement through the way the piece is moved by the wearer to put it on/off?
