The "Schizo Vase" is now available in white Expanded Polystyrene (EPS) as well as the original dark cork. "The outside shape is based on a Greek Amphora vase. The inner shape is inspired by an brass Indian flower vase."
They've also adopted the ribbed, dual-shape form factor as a pendant lamp (below). "The inner shape is a classic lampshade. The outside is more neutral, and looks a bit like a beehive. When turned on, the inner shape of the Schizo Lamp will be emphasized due to the translucency of the material."
While I understand the appeal of using EPS—the same compacted styrofoam used for packing and shipping applications—for its light weight, I must say that I, for one, feel that the 470€ (650€ for the vase) pricetag warrants a more substantial material, though I'm not sure what that might be...
In any case, OOOMS also offers a couple other, more giftable housewares in natural materials: the "Puzzle Board" is a neat little beech cutting board, which is not only modular but can also be used to hold a wineglass, making it ideal for your hosting needs.
The designers have also branched out into electronics with the "Wooden USB stick," another option in the 'things-that-look-like-other-things' category. Speaking of designer client gifts, OOOMS also offers personalized engraving (with a minimum order of 50 USB sticks).
