You could serve a 30-course feast prepared by the finest chefs in the land, but it will go completely unnoticed as long as your guests are sitting around this stunning Astrolab dining table from Roche Bobois.
Its see-through glass surface provides an unobstructed view of the table's polished gears, which are used to automatically extend and retract a pair of glass extensions on either end. It's one of those rare times where over-engineering is not only welcomed but also celebrated. Even if the Astrolab's complex mechanisms only extend the table by a metre, which is barely enough room for a few extra diners. [Roche Bobois via The Fancy]
