Are you thinking just patterns/designs, John? Or are you also thinking materials? I see a lot of pure wood segmenting, but not much with a combination of materials.
I've fiddled a bit in the past with multi-material segmenting, something I really want to get back into. Haven't had the chance lately, but I really want to give resin, trustone/fauxstone, wood, metals and maybe even other materials in a single blank a try. I don't want them to be gaudy, so its hard to design something that really works, but I've used acrylic, metal, antler, and wood in a single blank before. I'm no great blank maker, but I kind of like how the antler and wood went together, while I could have picked a better resin.
I also really like the idea of integrating little bits of trustone or something similar, in with a wood segmented blank, maybe along with some metal to separate the materials. Maybe I'll get a chance to explore all of this more this year.
My recent experimentation has all been with engraving and etching blanks. I don't think I've necessarily had any true successes yet, but I have plans...lots of plans!

I don't know if this kind of thing qualifies to what you are looking for. I guess, in fact, that etching or engraving could in fact be combined with segmenting to create something even more unique...
