Desnahemisfera designed a desk called Katedra from contrasting materials that even includes a built-in charger for cell phones (AirCharge). A curved white Kerrock surface is used for the desktop, sitting on a stack of wooden beams. The blocks are actually three opening drawers that are cleverly disguised. The AirCharge means your phone will always be charged. The charger is connected to an LED charge indicator that flashes white in standby mode and turns red when you set your phone to use it. When it turns green, your phone is fully charged. The idea is brilliant: it’s so convenient to work and charge the phone at the same time!
