I can't say I share your enthusiasm for that decorative scheme, but if you've seen that one in person and were impressed enough to want to emulate it, I don't understand your original question. You wanted to see sharkfin inlays - do you suppose they're going to look that much different than blocks? With so little contrast to the surrounding wood, you could probably have penis-shaped inlays made of that material embedded in that species of wood and nobody would notice. Also, it's worth considering why you can't find examples of what you're contemplating. Not that you need anybody's approval, but still. It says something that nobody does it when it's easy enough to do. I mean, you're not asking for anything custom. Warmoth will build what you want. Money's money, after all.
I'm sorry. Fuhgeddaboudit. I just realized I'm being a bitch.
