By Xavier Lust 2008. Virgo is a “living” structure which becomes a bookcase but, in fact, leads us to think about concave and convex surfaces relation as about the energy of a tightrope. The “composition of forces” is clearly expressed in the final equilibrium. The sculptural form of Virgo makes it usable both on the wall and, above all, as centre-room. Bookcase. Black anodised aluminium structure and shelves.
