I might be willing to give it a shot. I haven't had a lot of time recently to work on modelling and texturing, so you may have to bear with me a bit, but I think I could do it with a bit of effort. And there is absolutely completely and positively no way whatsoever to model this in Bryce. I'm sorry, but that kind of setup is well beyond Bryce's modelling capabilities (unless you want to spend several weeks creating it). Do you have a bigger picture of the object?
