The one on the shelf is probably a Akari paper lantern. I have an orange one that I quite like. You used to be able to buy them from Design Within Reach or the MoMA Design Store, but I can't find them on their sites now but they're on the Noguchi site. [1] The hanging sphere one might be similar.

For those not aware of them, Design Within Reach has a lot of nice famous designed furniture and shelving, but pricey. They often have 15% off season sales though. Good place to shop if you're into the stuff seen in this blog post.
