Dutch design boutique OOOMS first turned up on our radar last year for a few of their rectilinear furniture designs; they resurfaced a couple months ago, at Dutch Design Week, where they were exhibiting some of their clever housewares.
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).
