Well, Russell, hope you don't mind....and I hope you subscribe to the notion that imitation is the sincerest form of flattery. Here's my version of your design. I did cheat a bit here and there to make the design something I could handle. The joints are not nearly as tight, the legs are not curved, and the some of the edges are sharp instead of being rounded, but as they say...on a tall horse, in a high wind...and about 100 yards away, they kinda, sorta, look similar. (It really does have four legs, in case you were wondering...just an odd perspective.)
The wood is sapele, because I could not find a good piece of walnut at my usual supplier. This is my first time using this wood, and it is quite impressive in color and consistency. Maybe I will try a chair out of this stuff.
