Wow! These look stunning! Fantastic hunting :)
I'd be very, very tempted by these, even at $200. They're unique enough to warrant a price like that - being aesthetically so pleasing, and the tech of them too. I think the only problem I'd have is in choosing which to go for - I do love globes, but some of the planets, and sun looked great too. I really love the look of pool balls (spots & stripes), but I'm sure that, at $200 a pop, that's be one expensive look!
Having one of these in your home would be such a conversation starter too. They're very tactile and I think everyone would want to pick it up and inspect it. Not sure how you keep them looing pristine, but I think I'd spend a lot of time wiping greasy finger-prints off it/them.
Very nice.
