Here's the final result of the project with Kohler's Ken Hanna. Fixed up the geometry and did some fancy new renders with water, and the touch-control details on the sides of the bowl.
In case you're curious (or dubious), this is a photo of one of many experiments I did in the sink that ended up driving the form:
All of the water is wrapping around the outside of the metal, thanks to surface tension, even with a high flow of water.
Now... To finish that lamp... Just less than 3 weeks to go!
